Chip question, give me some imput on yours

[DavidTurbo//]

OK I've searched everywhere trying to decide between going APR or GIAC. I have a 99.5 1.8TQM and it appears that the GIAC would be a better and more fun chip although the APR states that it gives more power according to ECS tuning (214hp versus 200hp 93 oct). I think I am going to go with APR because I can do two programs, one 93 and one stock. I work an hour from home so as we all know with gasoline a $3.85 for premium and the amount of miles I'm putting on my car I think it makes more sense for me. Here's my question for you chipped guys! How is your gas mileage after your chip as apposed to before. Did you lose a significant amount of mpg's? How do you APR guys like your chips? Anybody experience both chips? Is the difference real noticeable? Lets see who rocking what chip and if GIAC really is more powerful and fun! Thanks for your help, can't wait to get more boost! these 5 lbs just aint cutting it!!!lol

I was getting an average of 23.5mpg on my 2000 A4 with GIAC. Forgot what the stock numbers are, but im sure it's nothing really noticeable.

i have an 01 1.8t with revo stage 1. FMIC and DV, and this weekend we had a audi dyno day at a local AWD dyno shop, and a buddy's car with exhaust, apr chip and intake actually made less power...quite happy with my revo, and half of the price of GIAC

[Stampy]

I have an 01 with APR 93. I got 397 out of my last tank. That works out to about 30MPG. If you beat on it all the time it will suck. If you drive normal, you get that.

APR is weak sauce though man. Atleast for the AWM. I think its more inline with GIAC for AEB's.

[fernando]

well i get between 500-550 KM's on a full tank, and i drive my car very agressive

Who sells revo? Havent really heard about them? How much power did you guys make?

[D's Avant]

Your mileage should not change too much with a chip once you get used to the extra power. The first few weeks you will go wide open with the throttle as often as you can to feel the little extra pull your car has. I get 31-32 mpg on the highway and say 20-22 mpg in the city. Just depends on how much you get into the throttle. I have APR in my 99 with no complaints and it pulls pretty strong with my RACE Valve. If you are thinking of going KO4 in the future get GIAC. I only went with APR because they were local at the time.

Damn I probably get that on my car! I get about 30 if I do strickly highway and 21 if its just city but I pretty consistently average 26mpg's! Sounds like what your getting. If thats what I can get with a chip I think I would go with giac.

NAH SON!!!
Doritos cool ranch
50 chips per bags

[DND]

I noticed a huge drop in mileage in city driving. The only way to avoid it is to stay out of boost but if you're doing that what's the point of chipping to get more boost?

[fernando]

the only thing that i don't like about GIAC other than being way over priced is the fact that the power band is not smooth at all.
With the Revo power ccomes in very smooth, and with the chip, FMIC and DV i made 163 AWHP and 213 torque.
I think that i could have done better but i'm having some boost problems.

[legionvr6]

60% highway. 40%streets. i get about 30MPG APR.

[DavidTurbo//]

Wow from what I've seen Revo is $500 and APR/GIAC are $400 each.

[creechsa4]

giac ftw! you're a aeb motor, I run the same motor. my buddy had a apr chip, while I had a giac. the giac had noticeably better power curve. the apr is a great chip, just the giac seem to getup harder.

[B5Jaeger]

Get whichever has a closer local dealer, esp. since you need a soldered on eprom...unless that's changed.

[This Is Epic]

If you're smart you would hold off, with gas prices everyday jumping 5-10 cents and with your drive you might wish you had those extra MPG's. Just my opinion. I've been wanting to chip for awhile now but I already average 5-600 a month in gas expenses.

I agree... the GIAC was more aggressive feeling all around than my APR. - don't forget the pc-16 upgrade is cheaper for your k04 in the future.

[m5racer]

here is my dyno i got APR 93+dv+borla exhaust+ intake
i really need an intercooler badly beucase my shitty stock one heat soakes instantly

Thats why I was thinking to go with APR because I can go stock for everyday traveling to work and put up the boost when I want it. the more and more I think about it the more I want to go with GIAC because of the power and I definatly want to get a bigger turbo later on.

haha you're the former apr guy! yeah we seem to play musical ecu's running each other's programming for 'testing' purposes. yah upgrading is easier on the giac files. whatever chip you get, make sure all your boost hoses & manifold hoses are in good shape. you'll quickly find out if they are bad after your chipping. i'm also still running a giac tuned ecu for 2871 for 550 injectors. still runs great!

[speedydragon]

Not sure if this is true for your 99.5, but for the dbw motors, giac is a 1.3bar file whereas the APR is a 1.0bar file. Giac is known to boost more aggressively and holds higher boost through redline. I am currently 17yrs old, and in chipped mode (APR) I'm geting 28mpg, mixed driving; and 24mpg in stock mode. Rest of my mods are in sig. I think the main reason why stock mode may use more guess is cuz of the stock fuel map and the fact that you don't get power until later in the rpms compared to chipped mode

Damn your getting 28mpg and u have a tip! Nice! It looks like APR in general gets better gas mileage. Maybe cuz GIAC boosts at a lower rpm thus requiring more fuel?

I don't think you will run in stock mode if ever once you feel the difference with a chip in full boost mode. I never, ever run in stock mode... Try pulling out into traffic in stock mode just once after you've been running with extra boost for a while. It will be scary... Did I leave the parking brake on??? Is that Ford Explorer going to hit me???

[prey]

GEt REVO, its solderless, they have a file for the aeb engine, I just had my 99.5 revo tuned and i love it.

go for it, you woudln't be happier.

thats why i went from stock to stage 3

[sageleo]

I use GIAC and couldn't be happier, when I first had it put in it felt like a completely different car.

[PerfCafe]

Its all apples and oranges. We loove revo here at the cafe, everyone here runs it, swears by it, dyno tuned and tested, the option to tune it afterwards with stage II software is killer even more so if you go for the SPS Controller! Power delivery is smooth and most of their gains are huge depending on your engine we've seen up to 65 bhp on some and 100tq gains on others! Revo knows their stuff. Bottom line is, software is one of the best bang for buck mods you can get for a turbo car.

[PerfCafe]

And remember the gains on REVO's site for your car are for Stage 1 only (stock car), Stage 2 when tuned w/an exhaust/intake etc. You can expect a 10-15% more horsepower on your initial gain.

Once you drive on the chipped file you won't ever use the stock file again, so forget spending the cash on that and buy something better with your money.

GIAC is a more aggressive file than the APR, APR is known for being conservative. I'd go GIAC if I had to pick between the two.
I went Unitronic instead b/c they're closer than anybody else, except REVO, and REVO sucks for anything but a basic tune on a stock car.

I picked up average mileage after the software, but I don't have either of the two's program. Same theory should apply.

IIRC GIAC solders in a new chip, as opposed to other companies, but that's your call. I don't like the idea, when the stock ECU can do what it needs to.

BTW I love being chipped, and I'll never go back... at least by choice

EDIT: If you ever plan on upgrading to anything more than stock I/C, stock injectors, MAF, etc. Do some research before you buy, REVO isn't as mod friendly as other companies. This is the reason I did not get REVO software

[UN-PIMP-Z-A4]

i have giac chip and i spike at 25 - 27 and hold steady around 20 - 21psi

[DavidTurbo//]

giac ftw! you're a aeb motor, I run the same motor. my buddy had a apr chip, while I had a giac. the giac had noticeably better power curve. the apr is a great chip, just the giac seem to getup harder.

Damn it looks like GIAC is what I'm leaning towards but What are you GIAC guys getting for gas mileage? I know that I want to put a front mount intercoooler and upgrade my turbo in the future and it won't be with a k04 just because if with the chip I can get 200hp and the k04 maxes out at 250hp, it doesnt seem worth it. I would just wait and get one of the gt series that can put around 300. correct me if I'm wrong

Actually let me clarify, does the k04 make 250 to the wheels or the crank? because a chipped car makes about 160 to the wheels and 200 to the crank

[creechsa4]

I got regular gas mileage about 25 mpg on my daily driving work and back on my giac k03/k04 files, gas will only suffer on heavy boost. just stay off heavy boost and you'll get camry/accord kind of mileage. k04 pc16 file is about 250 to crank.

[DavidTurbo//]

Ok I'm thinking about going with a unitronics chip so that later on I can get a gtrs turbo but I am having trouble getting in contact with them! Anyone running unitronics? do you have the their stock turbo or bt chip? how do you like it and hows your gas mileage? thanks! wanna get this done this week

[Squarrl]

i get 500km per tank city, and 750km highway.

[DavidTurbo//]

What chip are you running? Can you translate that to mpg?

[Tiluleshpingen]

i have giac chip and i spike at 25 - 27 and hold steady around 20 - 21psi

what!!!!!!! 27psi?[O_O]

[djwimbo]

what!!!!!!! 27psi?[O_O]

You're jealous aren't you

[Squarrl]

What chip are you running? Can you translate that to mpg?

Giac X chip

i think that works out too
20.8 MPG city
31 MPG highway

and i dont lay off the boost

[DavidTurbo//]

OK so after very much debate and research the winner is unitronics! I can use their program when my stock turbo tires out and I upgrade to a bigger turbo. I was thinking a gtrs or 71 turbo but thats in the future. At least I 'll have the program for it (just have to get it flashed again, supposed to be $200 additional) I would need to get an exhaust, front mount cooler and a few other goodies before that but I'm excited cuz i just got a reply from untronics! the guys says they flash the ecu through the obd port and it takes 15 minutes! 195 hp and 215 tq, which is not as much as the other programs but like I said it a stepping stone to the bt! There's two dealers half an hour away and another in the same town that I work in! Program is $500 for stage 1 and $550 for stage 1+ but I think the stage 1+ is only 2001 cars. They are Performancemotorworkz.com , swiftmotorsports.com , and namotorsports.net anyone ever dealt with these companies? Any recomendations? If I can go with the 1+ for $550 I think I'm gonna do that one!
