very very impressed!

AMS

Wait on the Chip before you upgrade you hardware...for example (turbo, exhausi manifold, intake, exhaust)

APR

The APR chip is not quite as smooth as the factory ECU. It's very powerful, and sometimes not completely smooth in the power band while accelerating quickly.

APR

Power increase over stock wasn't as impressive as everybody made out to be. Probably due to the 2001 model having 170HP, the change in power wasn't as noticable.

APR

Greatest performance upgrade ever performed...previous owner of a Dodge Stealth and this Audi kicks A$$.

APR

Noticeable improvement in acceleration, especially in 2nd or 3rd. Also plenty of power when passing in 5th gear.

APR

Smooth power delivery. Performance is similar to my '92 Eagle Talon Tsi!

APR

What the should have been from the factory! Tons of fun to drive!

APR

Turbo lag is a little more noticeable, but the torque and power increase are amazing. Feels like a small V6.

APR

The APR chip is not as fast as what i think. its say 200 hp but i dont think it is that much.

APR

Very smooth power delivery. So far everything about the car seems better!

APR

much better car with the chip. Only problem is it gave me just enough power to want more!

APR

What the car should have been for $7,000 more for only $500. Go Audi.

APR

Apr is the shit.

APR

Best $400 I have ever spent

APR

good chip

APR

LOVE my car, and the chip!

APR

I use 94 Octane fuel, I once put in 91 octane by mistake and the performace decreased ,turbo lag, sputtering,irregular boost between 4-6000 RPM along with decreased power output at this RPM. Even with 94 power still suffers slightly between 4-6000 RPM.

APR

None. The power gains are great. I feel like this is what the car should have running it to begin with.

APR

The '00 APR 1.0 bar chip truly changes the character of this vehicle. Driving is now effortless and acceleration is just a throttle tip away.

APR

I added a Borla full exhaust, with downpipe, two days later, which actually made the chip less fun, as low end torque decreases from the levels attained with just the chip.

APR

I replace the factory chip for servicing, and after the last trip to the dealer the lag that I complained about was dramatically reduced.

APR

LOVE IT. APR is headed in a great direction by constantly looking for new ways to improve an already great car.

APR

The team at APR really know what they are doing. When I had the dealer induced problem, one of their engineers helped ease my concerns with the chip possibly being ruined. They were friendly and helpful.

APR

The APR V3.0 chip IS BAD-ASS! 200hp and 245 ft/lb of torque!

APR

Nice 5500rpm shift-points. Only need to open the throttle 1/2 way for normal driving. Unfortunatly, now I cannot drive it normally. ;)

APR

All this hype, this much performance - Dont expect to much from a chip and youll be happy. (johnny bravo)

APR

I have chipped many cars and by far this was the best yet. Great power at the low end with more top end as well. Definately faster than any 2.8 or 3 Series BMW.

APR

The APR chip is so inexpensive, and makes such a difference, a new chip should be standard equipment. The power is great, the engine is smooth and the torque is magnificent.

APR

Love the APR Chip!

APR

The boost is quite sufficient for now. Money well spent.

APR

'00 Passat. I also purchased the spare ECU to avoid downtime and dealer service grief.This is a great chip and I would recommend chipping in general.Including suspension and tire/wheel upgrades this car has been transformed into an awesome vehicle.

AutoThority

Could never go back! The Autothority chip is smooth, rock solid and has plenty of punch where needed. A little pricey for a .8 bar chip, but a great investment.

AutoThority

Silky smooth just like stock, but kicked up to the next level. Way up!

AutoThority

I love the performance that the chip has given the car. I wish that Audi offered a tuner that they approved of, like BMW and Dinan. It is clear that there is a market out there of owners who want to personalize their cars.

AutoThority

Very smooth and responsive chip. It seems like that factory did it. No compromise in driveability.

AutoThority

The Autothority .8 bar chip is very smooth.

Garrett

Best chip on market.Tried Wett/APR/MTM. Garrett measures 20 HP more than any other chip tried w/GTECH

Garrett

Very torque heavy now! Less downshifting needed. Better driveability!

Garrett

set work great

Garrett

I could not believe the awesome performance! It is getting upgraded in a few weeks with more power and torque after a reprogram by Garrett! I am installing a Borla exhaust in a few weeks too!

Garrett

No one know's North American Audi tuning like Garret. He's been doing it for ten years, specifically for cars in the US, and he's very responsive to customer requests.

Garrett

I was going to get the Wett chip but Garrett has more boost, way more torque. Dick Chiang (DynoSpot Racing, Mountain View, CA) soldered it in for me. Now I'm smiling.

Garrett

Awesome, worth every penny!

Garrett

I previously had the Neuspeed chip. I wanted the Garrett Tip chip and replaced the ECU chip with it believing the combo would work better together. The Garrett chip definitely feels like it produces more power than the Neuspeed chip across the board.

Garrett

Once the idle problem had been resolved the power increase has been awesome.

Garrett

Garrett chip totally transforms the car, I should have done it sooner!

Garrett

My chip was done At Eurotech Atlanta.

Garrett

Purchased spare ECU for quick change back for service.

Garrett

I am totally amazed at how much raw pulling power there is now.I'ts almost like I have to be careful where I actually unleash this now. Nice predicament though. totally driveable, not much different than stock unless driven aggesively and then, whoppee.

Garrett

It's a must need for the A4 1.8

Garrett

go for it

Garrett

Although never 'denied' warrantee coverage at dealer, I am very cautious. Car will never go to dealer with chipped ECU 'in'.

Garrett

Mileage actually increased under normal driving! Maintains drivability, with kick lurking beneath the hood.

Garrett

Awsome upgrade! highly recomended.

Garrett

The chip has transformed my car. The surging problem which went away was worth the power gain. It has not returned. It is hard to drive the car without punching it, but when I do I have made it over 400 miles on a tank, 28mpg.

Hoppen (MTM)

Just fine chip from MTM.

Hoppen (MTM)

gonna do a diesel supercar! A4 2001 TDi 2.5V6 Quattro. around 240ps would be nice.

Hoppen (MTM)

No worries about engine damage, as chip controlls detonation VERY well. I see 16-17 psi max, mostly due to my exhaust.. LOVE it.. I want an S4 just so I can MTM chip THAT baby!

Hoppen (MTM)

MTM products are high quality

Hoppen (MTM)

Hoses come loose, poor mileage, hesitations, flat spots - about to change for APR

Hoppen (MTM)

Wheel well liner seemed to decrease hesitation when outside temperature was hot

Hoppen (MTM)

wonderful performer...

Hoppen (MTM)

Car kicks butt up here in the altitude, can run 95-100+ up Vail pass, 9 mile long 7-8% grade, no overheating or high oil temps pass tops out @ 10,600ft

Hoppen (MTM)

Love it and if I had the new S4 like Don P and others, I wouldn't hesitate to do the Stage 2 MTM upgrade that yields 320hp!! =) You lucky dog, Don!

Hoppen (MTM)

K&N Air Filter.

Neuspeed (Greedspeed)

not many miles on it yet.

Neuspeed (Greedspeed)

Wow, the chip alone really woke up the car. 3rd gear, 40mph thru 75 mph has a real 'oh my god factor'. Highly recomended. My unit cost only cost $170.

Neuspeed (Greedspeed)

Interested in the long term effects of the chip.

Neuspeed (Greedspeed)

Great reliable chip down to extremely cold weather conditions. Living in a cooler climate, I would likely buy a 1.0 bar chip next time as detonation is not a big risk for me.

Neuspeed (Greedspeed)

This chip has a smooth, crisp response when driving at speed. Turbo lag is reduced greatly, and driveability has increased! A great chip, at a great price!

Neuspeed (Greedspeed)

the chip is a greedspeed vbl .8-1.0 bar of boost

Neuspeed (Greedspeed)

Wow.. I got the new 1.1 bar chip from Greedspeed and all I can say it was worth it.. VERY smooth and responsive. Best money spent on the car so far.

Neuspeed (Greedspeed)

I really felt a huge increase in my low end, less turbo lag. Absolutly am loving my first, of many, upgrades!

Neuspeed (Greedspeed)

Upgraded chip and then the fuel pres. reg. (FPR)the 5 bar FPR DID make a diff. Gives good power (1.5 seconds off 0-60) Drives smooth, no surge. Gas milage equivalent. Idle may be a little rougher (not sure). Reccomended.

Neuspeed (Greedspeed)

It is an incredible difference! Very responsive and little or no lag. Chickened out at a silky smooth 125 MPH with about 15 MPH left in her....

Neuspeed (Greedspeed)

The car is truly transformed at 3000 rpm, much more fun to drive.

Neuspeed (Greedspeed)

This is a Passat report. Recently upgraded to 1.0 bar Neuspeed chip with addition of 5 bar fuel pressure regulator from .8 bar Neuspeed chip. Now much smoother torque curve, more low & mid range power, and turbo lag is almost totally eliminated.

Neuspeed (Greedspeed)

Any suggestions on exhaust or intake?

T.A.P.

get a 1 bar chip the extra power will be worth it

T.A.P.

Results could be felt immediately. Car feels much more fun w/this StageI conversion.

T.A.P.

Doing a turbo package upgrade in January Greedspeed's GS4 kit.

T.A.P.

When's my damn S4 going to arrive ??!@!

T.A.P.

yee haw

T.A.P.

Best results with free flow cat back exhuast.

Wetterauer

Enjoy the power but I worry about my engine and drivetrain over the long term

Wetterauer

The car felt like it lost 800 pounds once chipped.

Wetterauer

Peter @ Wett was very helpful. I had gone to the local Los Angeles Office which was a great benefit since they were able to see the problems I had and diagnose them on the spot.

Wetterauer

The chip claims to increase to 200hp and 236ft lbs tq. With the increase of tq i needed to install an S4 front sway bar. It helped alot. I have stock non-sport pac rims for now but that will change soon i hope!

Wetterauer

I know this has been said before, but the chip does transform the Audi. I had some doubt about getting the 2.8 or the 1.8t, but the chip relieves any doubt that I may have had!

Wetterauer

Gears 2, 3, and 4 are a lot of fun now, but the car retains its stock driveability under "normal" driving.

Wetterauer

Need to keep rev's around 2300 -2500 to realize immediate boost this Can be a bit hard on the Clutch. Otherwise: "what a kick in the pants!"

Wetterauer

Only thing I noticed, was that the (Tiptronic) transmission gets a little confused sometimes.

Wetterauer

wow. the chip made an *amazing* difference in the performance of this car

Wetterauer

My A4 was just another poky 4-banger before I installed the chip. What a great option at a fraction of the cost of a 2.8. I enjoy every trip to the grocery!

Wetterauer

My dealer installed the chip, and it is as though I have been given a new car since it was installed! The added boost is FAR too much of a temptation in heavy traffic!
