Chips: Poll with customer review
This has long been an issue with folks of B6/B7 S4 . SO IF YOU HAVE ALREADY GIVEN A CHIP REVIEW GOOD OR BAD PLEASE CUT AND POST IT HERE FOR FUTURE REFERENCE. ALSO OTHER MEMBERS PLEASE FEEL FREE TO POST PAST CHIP REVIEWS
Lots of good information that new members might have missed that have gone on in the past.
In the early days of the B6/B7 all of us were looking for any sign of support from the aftermarket. With the N/A 4.2 being such a tough nut to crack we didn't see much for a long time.
A little history
When we did the first thing to come out was as usual were exhaust. Oddly enough we were told how much power they gave us while still keeping the damaging Precats in. Come to only find out later. most Dp's with the Precats still in didn't do much power wise and actually over time seemed to do more damage then good.
Then cold air intakes, they looked real great with all the information showed from some of the manufactures. But still yet again when people really started looking it seemed once again this product wasn't living up to the claims. Some have actually seen a drop in power with the cold air intakes.
Chips:
Then came the chips. This is where I was really excited. We all know a real well done chip can do more then just make power for your car. at a cost of almost 700$ for sum chips I decided I needed to gather as much information as I could.
I really needed to dig as there wasn't much REAL conclusive information.
My chip Review
The entire reason I needed to do all the tests and look at as many chips as I could was because there was so much conflicting information. The dyno sheets from the companys looked great and showed all kinds of power. Yet when members got the chips many of them said they couldn't tell a difference at all. Further more some members dynoed there chips and saw NO difference at all.
It has been a tough time in the B6/B7 S4 we keep looking for more and under some rocks you find great parts. Still under other rocks you find performance products that are nothing more then marketing hype
While I feel dyno's don't tell the entire story this thread is for members to post there reviews and chip choice to further help new members know more about the chips and the choice chips that have tested and shown to be legit.

I after testing got the JHM chip Because there is more then just power and the JHM chip has shown to make the best power plus offers better drive abilty
Review
Throttle response.
Crisp and very spot on. The pedal isn't off set its 1 to 1. But the power and throttle are not delayed like before so it took me a second to get used to the cars almost instant reaction to my throttle input. The chip has eliminated the lag usually associated with the stock car
Power
JHM has a minimum requirement for there chip. They want the precat's removed and you can figgure out why. Look at your MAF readings and see how much more air the car is bringing in and you will see your going to need to get a bigger better flowing exhaust. The car has gobs of power down low and never stops pulling all the way to RED line.
driveability and excitement
The chip really makes the car come together like you would hope it would. The car reacts better and has a better power band. You will notice that the car makes better power at lower RPMs and requires less effort and less rpm to get around town.
Over all thoughts
Ive had my JHM chip for a long time now and its been able to make the most of every part I put on the car. While we have seen some people upgrade to headers and intake manifolds if they have other chips the cars are never getting full potential of the parts.
Ive gotten better gas mileage and clearly more power. Ive been very happy with the results and support Ive gotten from JHM and the chip

ok Ill make a RS4 poll and please just post if you guys have a chip. With countless chip question threads I felt this was needed for the B6/B7
WinterRunner So thanks for the APR RS4 chip vote. Ill add a post over there next week for the RS4
ATTENTION. PLEASE just try to post in the thread if you have a chip. I will work to keep this thread as on topic as possible.
RS4 guys please wait Ill post a thread over in that section soon. I haven't done so yet as its still less then 6months since most chips have been out for that car.

Justincredible, thank you for all the work you put into this platform. You honestly are one of the biggest reason I'm so happy with how all my car mods so far have worked out. I fucking LOVE my car, couldn't be happier with it. After reading your extensive tests and seeing the feedback from tons of members it was a no brainer. I went with JHM. My review?
Instructions for removing the ECU made it super easy and clear.
Next was getting it done, I shipped my ECU off to JHM, they opened her up and within 3 hours had it back in a box in the couriers hand. Can't ask for much more there.
Plugged it in. No CEL! YES! So that part works as promised.
Go for a drive, WOW! Huge difference. This is how a high compression V8 should feel. Why didn't Audi program it like this? The difference in torque was a lot more noticeable than the difference in hp. Sure it might be a little faster up top but who's butt dyno is that accurate. But you do notice when your lighting the tires up without trying. That never happened before. When people say they had to relearn driving the car they aren't kidding. You can't just mash the gas all the time knowing it will just slowly build up speed. If you mash the gas, the car jumps.
Throttle response is a 100x better. Before the car just never seemed right to me when I was playing with it in the snow, I could hang the rear end out but it just wasn't as controllable or progressive as in my old mustang with a LSD. After the tune it is a joy to drive in the snow, I think the difference is the throttle response, the rear end steers with my right foot now just like it should, I think the lag made it feel disconnected and just sketchy before.
No hassles, no quirks, no bugs...
If somebody does the research, looks at the hard data, combines it with the feedback from the members and doesn't end up deciding that the JHM tune is the only way to go then they are doing something very wrong. Probably need to quit reading QW for starters.

2nd both the statements
My review
After seeing one friend of mine get ripped off and scammed when he got a random "custom" tune that resulted in my buddys s4 MAKING LESS HP AFTER A BRAND X CUSTOM TUNE then stock it was kinda a no brainer that chips for these cars take more then just a fly by night want bee tuner
I also raced my friends giac chipped s4 vs my stock s4 after I beat him I was just done thinking that any old chip is going to work in our cars
I went jhm and f ya its beyond the real deal. No wasted dyno fluff no ms paint dyno sheets just good old results at the track and at dyno events
Each car is going to be different. You can't throw a chip in ur car and do no maintenance and no thoughts for what supporting hardware u have and think ur going to get the full effects of the jhm chip.
After my jhm chip install I didn't even know what to say. I was pleasantly wowwed
Power is second to non
Throttle and car response is amazing. If u hate ur stock throttle you'll love the jhm fix
Driveability really this was a great sunrise as well. The car does more then just drive great wot the car really has balls even pert throttle and at lower rpm range.
I raced a pes supercharged car with ny car and my car has headers and the jhm supporting mods the result was a very upset supercharged owner.
The jhm chip is more then just a chip its the key to your cars full potential

I have the GIAC flashholder with the 91 octane and race gas tune. Bought the car with it. I also have AWE dp and resonated exhaust. To be honest, I feel the difference with tune, but I'm not sure how happy I am with it. Sometimes if feels like the power band isn't really smooth. There is a jump in midrange power that kind of drops off. I didn't notice it as much until I started going to the track and throttle contol or maintenance throttle became more important. I would probably like to switch to the JHM tune based on all the good comments I've heard about it and they are located like an hour from my house. My only concern is, the car is still under extended warranty and I switch back to the stock program when I take it in for work.

I have run and driven other tunes and swithed to JHM this summer. The difference was truly night and day. The car responds and revs with an increased sense of urgency. You can feel the power no matter where you are in the RPMs. And the way the car feels when the manifold switches over brings a smile to my face everytime I drive.

Not a whole lot to add. JHM, after reading many, many threads on the subject. True, the top end gains aren't huge, but top end gains aren't huge for any of the cheap bolt-on parts, either (DP's, exhaust, tune). But for all those parts, the low end and midrange gains are whoppers, and the JHM tune is no different. Plus, their customer service is excellent. In fact, not only do you have to relearn how to drive your car after the tune, but the incredible immediate throttle response almost makes it more difficult to drive because it's THAT sharp. Going over speed bumps now I just have to slow down and keep my foot far from the gas pedal. Without the laggy stock pedal calibration, any slight touch of the accelerator pedal makes the car lurch forward.
But on the up side of that responsiveness, when you tell her to go, she doesn't think about it, check with her mommy, then snail mail you back - she just GOES! That and the very significant low end power improvement are the two main things you should expect from this, though you may not get them with other tunes.

JHM tune. I was told it made a difference, but don't expect too much, so I went in with high hopes but realistic expectations low (we're not a boosted car where a tune just gets you 40whp after a tune). All I can say is, that even though it's not a huge surge of additional power, it completely changes how you can use the power you actually have and as mentioned, I had to almost relearn how to drive the car. Vey happy with it and wouldn't even dream of going to another tune, especially as you add new performance parts, you know the JHM tune is going to be there with you to grow with them.

I enjoy Lay's Kettle Cooked Sharp Cheddar chips, very yummy...
As far as my tune, the JHM 93 was awesome. It carried through with all the modifications that came after and was always very quick.
I'll dig up some of my thoughts from Summer '09 and repost them.

I was running Revo for a few years before I went JHM tune but i did headers the same time so i do not know what it felt like with the just the tune being switching over but the difference was TREMENDOUS and Im pretty confident the tune was what pulled everything together. then when i got my updated tune along with the JHM IM is when the throttle response became almost BMW M like. incredible and just the way it should have been from the factory.
The sad part about this thread is that quite a few people will never see it because they have their heads shoved SOOOOOOOO far up their own asses (quattroworld members) that they refuse to take JHM into consideration becase 1. they dont have that sexy big tuner name like GIAC/APR and 2. that forum is run and moderated by a ASP employee but thats another day...
If anyone has not driven a proper JHM bolt on car, please do yourself a favor and do so. Go test drive cars with all different tunes and mods and Ill fucking guarantee, the JHM car will blow you away.
And other than JHM, Justin is the best thing that ever happened to this platform so all you new guys get acquainted with him and RESPECT him, he's a valuable asset

went from Revo to Unitronic and now to the JHM tune. The first time I drove the car with the JHM tune I was surprised by all the torque added in the low RPM range; it's true that it takes less RPM when driving around town. I actually had a chance to run against a stock car and completely destroyed him. Get the JHM tune.

I originally wanted to go with the APR chip because of the anti-theft features and that I could adjust it through the cruise control. But after reading the chip comparison I decided to wait and boy I'm glad I did. The JHM chip did put a smile on my face. I know this sounds redundant by now but it did change the car and I did have to kinda relearn how to drive it but it was just a matter of minutes for me. It pulls to redline a lot smoother than stock. Gas mileage also went up a bit. Before the chip I would get about 15 city and 20-21 highway. Now I'm getting 17 city and 25 highway. It might not seem like a lot but remember that I drive it a bit more agressive after I got the jhm chip along with the fi catbak, piggies and bmc filter.

Sent my ECU Monday morning to JH Motorsports - received it today. Installed it and noticed a difference immediately; especially in the higher RPM range. No, never had my car dyno'd but I will be happy to report my next track event 1/4 mile time...especially since I have the worst reported time on the damn sticky
I don't know if GIAC got the tune right w/ the B5 models so I won't bash too much. Who knows how much time they put into the tune. I guess Jason either put in much more time to find the right tune or simply understands what works.

Hi audiziners,
OK, I have it installed the JHM tune 2 weeks ago, I can enthusiastically recommend this chip to other B6/B7 S4 owners. My tiptronic car is moderately modded with B7 S4 Avant, Miltek exhaust, CAI, PSS9s, Addco RSB, EHS Porche Cayenne big brake kit. Of course the CEL is gone as expected, but the car has a transformed feel. The throttle response of the stock OE program was most annoying, it seemed that the electronic throttle was asleep and needed a good boot to wake up. Now the car responds immediately to throttle input, perhaps a bit too much for the first 2 mm of travel, especially when cold, but once I got used to the new setting, it transforms the car so that it feels eager and ready to go.
Obviously quickening the throttle response will make any car feel stronger, but the chip clearly is putting out more power across the range. Acceleration from a stop now dominates other cars, (a new series Mustang GT this AM), but midrange and high end power all feel much stronger. I know people want quarter mile and dyno numbers to compare actual performance, but for those of us who bought the car as a daily driver looking for sports car performance with practicality, a JHM chipped S4 provides accessible performance you can enjoy every day.
An added benefit is that I am seeing a 0.75-1.5 mpg improvement with the chip, a surprising effect with the increased power, but it probably makes sense because it optimizes the fuel/air ratio of the modded intake and exhaust. This benefit of improved fuel mileage alone helps to offset the cost for the tune.
As other Audizine members have said, I wholeheartily recommend this tune to anyone who considering a performance upgrade to realize the potential of these great cars. Thank you for this great product!
Sincerely,
Caraddict

P.S. A couple suggestions regarding the instructional video on removal and replacement of the chip:
1. I used a dremmel with a cut-off wheel to slot the head, it was much easier to control, threw up a much smaller spark, and was extremely accurate. I practiced with a grinding wheel on another screw first and made the slot too deep, which is why I went the dremmel route.
2. The back right hold-down screw on the cover was particularly difficult to access, but I found it much easier to get at when I used a light and my right hand to place the torx into the screw head, then with an extension I used a 1/4 or 3/8 ratchet THROUGH THE WIPER BLADE HOLE to turn the head. Maybe you can add this suggestion to you instructions to help get at that cover screw. The back left screw was much easier to access with no extension, just a 1/4 ratchet and the torx head coming from the left side.

My S4 had the GIAC chip on the car when I bought it, so it had been a year since I drove a stock B6 S4 (cousins).
I was happy enough with the car in general, but I could tell from people's descriptions of their cars that my car wasn't maximized (FI exhaust. xpipe.)
So, I added the JHM chip and the JHM intake manifold. AWESOME.
Soon, I will be doing piggies and I expect my smile to get even larger.
I would only be reiterating what others have said about throttle response, etc. So, I won't do that. All I can tell you is that if the cost was $750 versus it's current $450-$500 range, I would be just as happy. Best thing I have done to my car. PERIOD.

After reading tons of posts like these^^^ I went JHM with the supporting mods (2.5 in cat back and piggies). Have not tried any other tunes on this car for comparison, but i can say:
1) Love the improved throttle response.
2) Power band is smooth
3) Noticeable (but not large) power increase (especially down low).
Headers- here I come

Got flashed with APR and couldn't tell anything difference. Got flashed back to stock. Looking for a JHM tune in the next few weeks Ive driven in a buddies car that has a JHM chip and its a crazy large difference. I was very pleased once I felt it.

I just wanted to say that the difference is completely night and day, and it is the best $500 I've spent next to my APR flash on my A4. The throttle response is completely changed, I sprang forward in 1st gear trying to get out of the JHM parking lot, looking like an idiot that can't drive stick. Yes, it will do that to you. Every gear feels faster, the RPMs jump so much quicker, and 6th gear has pull! 3k rpms in 5th feels like 5k+ in 4th gear at WOT, and that goes for the other gears as well. If you have a B6/B7 S4 with piggies/DP's, get the damn tune!! Take my word for it. Thanks JHM for supporting our platform!!!!
And also want to give them a shoutout for spotting/fixing a vacuum leak that I would have never found!

Every gear feels faster, the RPMs jump so much quicker, and 6th gear has pull! 3k rpms in 5th feels like 5k+ in 4th gear at WOT, and that goes for the other gears as well. If you have a B6/B7 S4 with piggies/DP's, get the damn tune!! Take my word for it. Thanks JHM for supporting our platform!!!!
And also want to give them a shoutout for spotting/fixing a vacuum leak that I would have never found!
I couldn't have said it better! My hubby just got my B7 S4 tuned for my grad/bday gift and oohwee!! Why didn't I do this sooner.. I had a catback and intake before the tune.. got a ported throttle body, intake spacer, piggies and tune and it is a night and day difference. I love it..thanks JHM!

Went from a Stasis/GIAC tune to JHM. Total path was stock/Stasis/stock/JHM.
My experience was per the note on the JHM website on the tune page; "So far we have ran into some issues chipping some of the GIAC and REVO multiple program ECUs..." My ECU HAD to get it reflashed back to stock before the upgrade. I actually hand carried my ECU to JHM told them what it had on it. They told me it would either work or it would not. It did not.
The reflash added about a week to my downtime.
Whatever. It was totally worth it. I am most impressed with the way my car just pulls and pulls and pulls through gears now. It is night and day different than the Stasis/GIAC tune I had before which was only mildly hotter than stock. The jump from GIAC to JHM was exponentially greater than the jump from stock to GIAC.
The JHM tune is all that and the dime for a cup of coffee (and more.) Would not kick it out of bed for coming in with crackers. A real game changer.

There is a tune for 91 octane fuel and a tune for 93 octane fuel. IIRC since you are in california, you guys dont have 93 octane fuel...thus the reason for the previous owner to get the "mild" 93 tune...???
thats the only thing I can think of.

JHM here. few things I noticed:
1. you will look like a dummy if you don't relearn to drive your car.
2. throttle response!!!
3. rpm bounces around on cold start up. witnessed other jhm S4's doing this. common issue?
4. didn't see my gas mileage go up...this can be subjective.
5. my check engine light for o2 sensor came on...prolly bad o2...
6. does not leave you satisfied. would header and IM fix this? or just leave you hungry for more?

1. very true
2. very true
3. this is a cold weather thing, popular on B7 S4s. Going catless or piggies exacerbates it. Happens on channad's stock S4 (and on mine when I was stock)
5. CEL for what? post it up. I was fine with piggies and tune...but when I went 2.5" catless a sensor died (B1S2). Easy fix.
6. no matter what you'll always want more power. Trick is to mod in steps so you are always feeling something new. Getting it all done at once and you'll lose appreciating the various mods. Intake is awesome...I don't have one but it certainly works well with other mods like DPs and headers and superchargers etc.

After a few months of driving with my JHM Tune I have short pro and cons list I want to add
Cons:
Not free
ECU removal and chastity belt can be a pain
Can’t be flashed from OBD-II port.
Downtime
First two weeks, car feels like a Toyota with unintended acceleration.
Car can be a bit touchy from a stand still, it feels like its always in drag mode
No Multiple programs, or go to stock.
Pros:
Throttle response is very close to a TBC (Throttle by Cable) car
Smother Power delivery (not as peaky)
A bit more TQ down low and some minor extra power on top
Overall the car feels faster pulls harder
Managed a 4.7 0-60mph (4.9 without tune)
Power: JHM Supercharger Stage I, Intake Manifold Spacers, Carbonio-JHM hybrid Intake, 034 MAF Hose, FI Downpipes & Cat Back, Carbon Fiber Vented Hood
Power supporting: APR Snub, 034 Engine & Trans Mounts, Apikol Rear Diff Mount, JHM Oil,Power Steering & Trans coolers
Handling: PSS9 Coilovers, Hotchkis sway bars
Brakes: B7 RS4 Front & Rear Brakes, StopTech SS lines
Daily Driver: BMW E92 335i Coupe, JB4 stage 3 piggyback, quaife LSD, 440hp on 100oct

its simple. see my member number...its not braggin rights...its just to say i've been around a long while and have seen it all.
and way back when...it was kind of my goal to show the community that what was being offered to us was doing nothing for our cars.
I wanted the companies to set their game up...as I wasn't buying what they were selling.
how did i set this up....i would go to meets and race friends who bought into the hype. i've drove all them....unitronic, revo, apr, giac.
raced them all. other than increased throttle response...and from what i felt...it wasn't a big deal. nothing translated to gains on the street.
while i think i'm a better driver than most, people used to call my car a freak of nature. saying it was a naturally faster car from the factory.
which wasn't the case...my brother ends up getting a b6s4....not the best driver....and we've raced a billion times from a billion different ways...
guess what...we were even. so all that money we were wasting...wasn't translating into power on the street.
MLR was a story i posted way back who paid serious bucks and had it sit on the dyno till it made power...took 3 days with the dyno tuning.
Before the custom tune chip...he was custom dps and custom exhaust. Car was dyno'd stock...car was dyno'd after dps and exhaust...barely yielding any gains above stock. the cost certainly didn't justify the gains or lack thereof. So he went to tuning and took a long while to get it to make something...they had an RS4 stock dyno on the charts and they threw it up against it after days of tuning and got it close to an RS4. CHP was calculated at 402HP or something close...but he had my TQ than the RS4 showed....or so says the dyno.
so i met up at a meet with MLR after his car was done to race stock vs modded. the result was....we were tied....if i wasn't a lil quicker after the honk...i would kinda nose up a 1/4 fender. sometimes i wouldn't. what we agreed was that the car was optimized from factory and what we were doing...didn't do anything. me being a prior GIAC fan boi if you will....i looked to them first and i didn't feel anything.
I had my brother go REVO for hopes that with his MILLTEK CB he would beat me...nothing. REVO offered multiple settings to adjust....we flashed and flashed....nothing had him gain over me. So left my car alone. sure cars sounded nice...but i wasn't paying for sound. i am all about performance.
JHM was making headlines in the B5S4 forum and decides to take a crack at the B6 S4. well he got it. NO JOKE hands down...his tune is magic to our car. gains to be had...throttle response was waaaay up. this is what i heard. then i get a message from justincredible. long talks and he has he has a flash...he said he gained 3 tenths from just ECU swap....i ask...they only way to really know this...is to do it same time at the track and swap stock for modded ECU and make a pass...he actually did this with video. he sends it to me. i watch...i said finally someone has done it and made gains over stock. but this is where we talked about the right parts...more of a science to making the b6s4 faster. at this point i'm last to the game....everyone has JHM tune....and rightfully so. NO BULLSHIT...JHM brought us parts through research...because people like me...only cared about real world gains/differences. not dyno numbers.
Finally I was ready to get back into the game...and before i thought my car was nice stock...its quick for a 4000lb car. i enjoy it everyday i get into it. after my parts i've added....its completely a different beast. definitely quicker...noticeable. not some placebo effect. but the real deal. and JHM slowly starting adding parts and parts and parts. and i've followed the whole time...just became a lurker on the forum. see whats new. the tune is like no other...its the real deal. gains to be had...but you also need supporting mods. supporting mods on the other tunes did nothing.
when i raced that s5 on the highway the other night...i first had got to see what a difference these couple parts made. that sexy s5 was something in my rearview from the second i hit the gas. i had previously raced another s5 on a nice summer day from the dig...and we were dead nuts even. now...its not close. but the effets of the tune on the parts...its night and day compared to the others. and thats speaking from experience. i love the fact that someone (JHM) has been so dedicated to making the b6s4 better and faster....because what he's done....has actually made a real world difference.

Like "boost" said in the above post, I too have been on this site a very long time. Although I am not a very mechanically inclined person(I do not work on my own cars) I have read just about every relevant(and sometimes irrelevant) post on here since joining. It has kept me informed in a way that no other medium could have on our car and I am very grateful to Audizine for this.
When I got my B7 S4(4th Audi) one of the first mods that I purchased was the Labree downpipes and exhaust. This was again after a copious amount of reading on actually all of the forums and my conclusion was LaBree. What a beautiful piece of crafted metal. I was like a kid on christmas when I watched them being put on. And Holy shit did it sound good!!! I am truly happy a happy camper since 2006. I get ridiculous amounts of compliments from young and old, male and female people on the way my car sounds, and it was truly a performance mod that performed. Dyno video to prove.
More to the point of this post, 2 years ago I flashed my ecu with GIAC and I honestly could not get a real feeling for the difference. I would venture to say that there were some top end gains(butt dyno) but that was pretty useless as it does not apply in every day driving. I followed the early growth stages of JHM and added mods slowly from them.
Intake spacers
LW crank pulley
LW rotors
At that point the software had not been readily available but I began to read more and more as it slowly disseminated thru the B6/B7 community.
I ultimately just purchased the chip and all I can say is WOW!!!! It is by initial impressions the most transformative thing that I have experienced on my car yet and therefore the best value for money spent.
I will continue to follow JHM as they endeavor to officially launch the supercharger soon and eagerly anticipate my participation in that program as well.
There has not been another company in my laymans experience that have provided so much contribution to this long ignored 4.2L community and I am really excited to see what is coming next!!
Fly's LED V4 mods, RS4 Black out grille, Full Labree exhaust with straight pipes, JHM L/W crank pulley, JHM intake spacers, K&N filter, JHM knurled shift knob, JHM L/W Frt rotors, Hawk carbon brake pads, Strat short shift kit, JHM tuned, Bilstein PSS9, 034Motorsport adjustable control arms, VMR Blk Onyx V708's

I was originally from the B5 family(am now a B7 owner) and have been a big GIAC fan. After reading this, JHM seems to be the clear choice. NOW, can anyone point to a distributor in the NorCal area? Thanks guys :)
B7 S4 - needs go fast bits :)
B5 S4 - sold :(
