To be fair bud, your slow car is probably the closest car here to EA’s b7 with your 6 speed ZF 😜

LOL yep my dad gave my daughter his blazer went up there to get it 3 miles from his house got tagged by a buck. 45 mph road i was doing like fifty saw him slowed down to about 20 he was just standing there on the side of the road then jumped out in front of me. slammed the brakes and he was halfway stuck kind of under the car when i came to stop(icy road) reversed a little put in park then opened the door. when i opened the door he jumped up looked at me like i was stupid for about 15 seconds then ran off. When i was in highschool guy in front of us hit a deer on route 30 flipped over his car head hit the hood of our 78 rabbit and broke off the antler in our hood and flipped to the side of our car. think my dad still has the antler.

Too soon.....

I was doing some maintenance on my dads car (my old car) A4 Ultrasport GIAC K04 6spd man....Took it for a night mission “test drive” to the car wash. Hit and run by 2-3? elk and this was the results. Just finished fighting with the insurance company, sad to see her go.

You actually think a pre facelift B8 A4, the most problematic A4 in the history of A4’s, is FAAAAR superior to B7 6MT Avant? You’re on drugs right?

It’s that Typhoon intake I guess. 🤣

Talking with Tyler he thinks the extra maf may be because of cam angle at some point will try to log it with vcds. who knows maybe the higher maf is making less power than when it is in the 290s hard to say without dyno. Are you running meth also or just ethanol with the 100 file? Boostane came yesterday will hopefully try the 100 file this weekend, Joel (from IE) emailed me and said boostane will not prevent knock in the 100 file, only one way to find out . Funny that now everyone talking about APR tune being strong now, if OG wants to chime in back in the MK4, TT and most of the 1.8T vortex forums everyone with APR was bitching because the other companies tunes were stronger.

I don't want to be negative just try to be constructive:
- from literature 320 G/s is out of compressor map efficiency so yes 290-300 G/s could make more power. With a good tune 290 in the efficiency area of compressor map should allow you to run more timing than 320 out of it.
- I did dyno and my max power is at 6200rpm even if MAF continue to climb until 7000rpm. My max MAF is at 6900 rpm bit their on dyno I make 20Hp less than at 6200rpm.

So yes you should dyno it. Not for the hard number as every dyno read different but more to see the shape of you HP and torque curve.

APR has always made reliable, high quality tunes that work right. My MK4 GLI made 215 WHP and 240 foot pounds on a Dynojet with the APR stage 2 tune with APR V Tune software in 2006. You really have to be an OG to even know what V Tune is.

That tune was not weak. At all. 55 wheel HP over stock.

And here’s a post comparing the top 3 B7 off the shelf tunes with logs and dynos from the same car. The owner liked APR the best.

Apr is also known for blowing a few Audi’s up and a lot of people haven’t forgot.

Last year around this time unitronic was telling their customers they collected logs for apr tuned rs3’s and they were all running dangerous lambdas.

They were passed around in a big group chat and never went public but you’d hear people talking about it.

To be fair blowing shit up is part of r&d... gotta find the limits


So I tried to install my ptp turbo blanket but am finding it near impossible to fish under the turbo between the motor mounts. The stainless clips get snagged on everything and make it very difficult.

Still have it apart may try again after a little break.

I was able to get the cat wrapped with lava wrap without having to pull the down pipe. Guess that’s a small win.







This was the first wrap I’ve ever done. Think it came out pretty good for doing it with the downpipe installed

I see there has been a lot of crap flying around over the last couple days about some of the tunes being trash. I suspect that most of the tunes are reasonably decent when used with the correct (intended) parts. It’s probably the mix & match that is causing most issues (waist gates set wrong, odd ball K04s variants...).

Even with the not perfect pairing, almost nobody is complaining about how their tune drives at WOT. It’s the part throttle hesitation, surging and flat spots that people are complaining mostly about.

In a lot of ways, my not perfect part throttle power delivery is my own fault. I wanted MAX power, so I chose my own parts based on what I though would give the most. HPA’s manifold combined JHM’s turbo has not performed as it should because there is no off the shelf tune for that. I originally used HPA’s software with my combo, but it was wretched. The only reason I got the manifold was so I could install a complicated port methanol system to run a really aggressive tune.

At WOT my car feels very fast (even without meth) with no issues at all. It’s the flat spots at somewhat high torque loads that are the issue I am trying to solve.

I have had major surging problems on HPA’s and early Malone tunes under heavy torque demands but that was reduced to intermittent hesitation under moderate torque in later Malone variants .

As a side note, Malone did say the K04-R does not behave like a regular BW K04. That’s why I was asking earlier about who has had good results with no driving anomalies using the K04-R with APR tune.

Honestly, I really don’t want to ditch my Meth setup to return to the stock manifold, but am considering it.

HPA manifold on VW R32 was a disaster. Lost crazy amount of torque mid rev and almost gain nothing at top rev. I just hope for you it's better on the B8
But HPA left me the taste of a company who had no idea about what they do with Intake manifold.

Yes either the APR or IE tune will perform fine for the majority of cars out there. Not every car is going to respond exactly the same just look at spark plugs plenty of guys here run the breix7's with no problem, when i pulled mine they were all completely white so change to the 8's which have worked well in my car.

I have heard good things about malone are they still trying to work it out? What is your current meth set up and where did you mount everything?

And in case everyone missed it when spawne mentioned it the other day HPT lowered cost to 2 credits for our ECUs.

I know bb-tt has someone doing some remote tuning for him with iterative updates as he hunts for the ragged edge, and I think Spawne might have jumped in with them. I've been quietly following along, hoping they're able to build something solid that the developer would be willing to then sell to others.

Until I can get the car to them, I don’t think they can do much for me.

My meth setup includes one nozzle at the intercooler exit and a very small one in each intake runner. The controller is an AEM unit that is based on MAF. The port nozzles are set up as a second stage to come on at a specific PSI (assuming the AEM unit is seeing enough airflow).

Honestly I don’t remember the specifics. It’s been almost 2 years sense I last messed with it. Without the base tune being dialed in fully, it did not make sense to try to work on a meth tune.

I have been driving around my 2018 Q7 that I bought 18 months ago and patiently waiting on the restoration & modification of my 1991 Saab 900 Turbo. This has kept me entertained enough not to think about the Avant much.

If you search my name, you should be able to find my abandoned meth injection thread. It should have most of the specifics and photos. I still plan on finishing thread some day.

I recently switched tunes from a custom Malone to APR K04 and have been doing some logging on the 100 octane tune using WMI.

I was studying the logs (timing pull & such) and noticed the drop off of pressure with the K04-R is a lot more than I would have expected. At about 6300 RPM the logs are showing 1920-1980 hpa max. That’s only about 14psi after subtracting atmospheric pressure. The N75 duty cycle peaks at 95.7 at about 5000RPM and stays there.

Before anybody asks, My wastegate cracking pressure is 7.6psi.

Is this what others are seeing with their regular K04s?

I am posting this more out of curiosity than anything. I have a boost gauge in my car but don’t stare at it doing 80mph on back roads. If someone asked me, I would have thought it was about 17psi. Before replying, please look at your logs.

I have the ZF8, so unless I am manually shifting, it auto up shifts at 6100, so in normal use I never would have noticed the drop got that extreme.

The car runs like a dream, (now that I am back to APR). There is nothing wrong with the car, the tune or anything else. It’s just clear that the K04-R is not up to providing high RPM boost like I would have liked.

It’s also too bad that a JB4 can’t advance the timing on the B8. The custom tune shined in that area relatively speaking but can’t touch the midrange punch of the APR 100 octane tune on meth. Although the top end power of the 100 octane tune is still higher than the custom tune on pump 92, I can tell that there is a lot left on the table without more boost or timing.

[EvolutionArmory]

It’s not unusual for a 100 octane tune to taper the boost down towards redline due to the higher requested timing.

I have a B7 so there are differences in what our cars can make for power but my 93 tune makes more boost at redline and only has 11.5 degrees timing advance and on 100 octane my boost tapers down a little but am making 16.5 degrees advance.

I don’t think your issue is too much of an issue. Do you have Draggy? Buy one and do a run if you don’t have one. Maybe you’ll be pleasantly surprised at what it does.

I tried APR’S K04 file (free money back guarantee) with my BW K04 and my logs showed 18 PSI at 6200 RPM. It had good power in the low to mid range but I switched back to my custom tune because of the lack of top end power with the APR file.

That was the reason why I opted for APR vs the other OTS tunes. I read that they're more conservative in terms of power. But they have the best low-mid range.
