This is under serious debate so there is no clear answer. A lot of people, though, swear by MTM with its relationship to Audi.

Zak adds: "APR (Audi Performance Re-engineering) makes excellent hi-performance chips dedicated for Audi's as well, gave my TT-225 an extra 42HP for around $500."

Nathan adds "Revo the only way to go. 225hp-265hp torque 207-284 that is a big difference. also its not scannable if your scared." - 5/22/2006

Jaks adds "My brother in law is german an he lives near cologne - he went to mtm and they tryed to optimise his TT - TWICE without success ... after that the put back the orignal software to the computer and they didin't charge him anything ....

there are hundrets of chip tuners in germany - but there are less than ten in whole europe witch are really good.

one of the best is Thorsten Wimmer in Solingen, Germany (www.wimmer-rst.de)

he is maybe the only one who has realistic horse and torque values advertised." 6/17/2005

Tires should last between 10,000 and 30,000 miles depending on the use and type of tire.

Since performance tires are made of softer rubber, they wear quicker so you will not get the same wear as a pair on a Honda Accord. Also, tires are sports cars seem to be used a lot harder, which we can't imagine. :)

Read up on the tires before you buy them, see what others are getting for performance and wear and buy accordingling.

John adds: "I have a 3.2 DSG in the UK and my tyres are about 75% worn after 15000 miles. Most of my driving is long distance." - 5/10/2005

Jenn adds "Putting fresh tires on the car will not resolve the alignment if it is off. Caster (usually factory preset), camber and toe must be reset... also, I find that my low profile Potenza's on 17" rims need constant tire pressure attention...If you aren't checking tire pressure at least once a week, this could be why your tire(s)has(have)worn unevenly..." - 12/9/2004

I have seen a large range of numbers for 0-60 times and here they are.

Best - Worst : Model
6.9 - 7.4 : 180 Coupe
7.0 - 8.5 : 180 Roadster
5.9 - 7.0 : 225 Coupe
6.2 - 7.4 : 225 Roadster

I am sure that if you dump the clutch at 4300 RPM you can hit the lower numbers.

Thanks to Bob for the fast vs quick update.

Yes & No.

A "chip" is just a computer chip that controls all the of the functions of the engine. Most chips do minor tweaking to the timings, fuel mixtures, etc to get the most out of the engine. That, in itself, does not hurt the engine.

Some chips though, remove the redline limit, meaning you can now rev your TT over 7,000 RPM. This could hurt your engine in the long term.

Utilizing Jim T's math and dyno data from Garrett, supplied by John S, I went through the exercise of generating 'walls' of RPM
& torque numbers for the TT 180 engine. Initially the goal was to determine optimum performance up-shift points (read as 'Drag
Race') through the gears. I confirmed through Audi USA the following gear ratios (which are NOT published in either their slick
sales brochure, nor in the owner's manual):
1st: 3.3; 2nd: 1.944; 3rd: 1.308; 4th: 1.034; 5th: 0.838
As described by Jim T (1/26/2K), there is a theoretical rev point at which the wheel torque loss across an up-shift can be
equalized(wheel torque loss at zero). I call this 'torque unity.'

SHIFT TORQUE UNITY RPMS (approx.)
----------- ---------------------------
1>2 unavailable at or below 6600 (31 lb. loss)
2>3 6475
3>4 5980
4>5 5920

Two posters opined on this matter in less empirical terms. Ted's (1/25/2K) seat-of-the-pants experience suggested 1>2 @ 4K; 2>3
@ 5K; 3>4 @ 5.5K; and 4>5 @ 'RED.' Ted's version translates into the 'walls of data' as:

TED'S RPM RPMS DROP TO TORQUE LOSS
----------------------------------------
1>2 4K 2360 226 lbs.
2>3 5K 3360 81 lbs.
3>4 5.5K 4350 16 lbs.
4>5 'RED' 5350 passed thru 'unity' @ ~5920

Marius B's post of 1/26/2K recommended a 5.8K shift point, with a predicted drop to 4K in the next gear:

MARIUS' RPM RPMS DROP TO TORQUE LOSS
-----------------------------------------
1>2 5.8K 3417 110 lbs.
2>3 5.8K 3903 43 lbs.
3>4 5.8K 4585 6 lbs.
4>5 5.8K 4700 2.75 lbs.

Although this thread began as a performance optimizing investigation/validation, addressed more directly at the 'need for speed'
group, I dove into the exercise with an additional agenda. My opportunities -- combined with good judgement and semi-balanced
sensibilities -- for using this knowledge in my small midwestern town -- of flying away from a stop sign at 5K, seeking the 'unity'
torque loss shift points -- are minimal. So, I asked, what are the brackets of sensible and judicious shifting in the day-to-day
driving of my TT, verses chasing the performance optimum? I've divided my thoughts on this into three groups: 'day-to-day' --
safe & conservative -- the cops could watch you wheel through these and not bat an eye; 'fun' and marginally visceral -- makes one
feel some G's and sneaks a peek at torque unity; and 'I wanna race' -- let's push the envelope of the stock 180 TT.

=1>2=
DAY-2-DAY
Get out of this gear soon -- it's too low... shift away before 4K, RPMs drop to ~2350 in 2nd and torque loss is about 225 lbs.
FUN
Run it up to 5900, RPMs drop to 3480 in 2nd, torque loss is under 100 lbs., and you've probably exceeded all reasonable city
speed limits.
RACE
Redline for a great 'hole-shot,' slidin' the clutch at start-up (see Marius B's post of 1/26/2K).

=2>3=
DAY-2-DAY
With data saying 3684 equals 30 mph in 2nd gear, try 4100 where RPMs should drop to ~2760 in 3rd and torque loss is under 100
lbs. I sure like this gear...it speaks to the seat of my pants...so for
FUN
Run it up to 6K where RPMs should drop to ~4035 in 3rd and torque loss is a reasonable 30 lbs.
RACE
Pushing it to ~6475 hits torque unity and RPMs in 3rd should drop to ~4350.

=3>4=
DAY-2-DAY
This one is difficult for me since one can move around town all day in 3rd with this car and look law abiding and feel and sound
good at the same time. I'm experimenting with a range of 3600-3900, with 4th RPMs dropping to the range of 2850-3080, and
torque loss at 45-39.5 lbs. respectively.
FUN
At 5500, RPMs should drop to ~4350 in 4th and torque loss is about 16 lbs. This agrees with Ted's suggestion, and we're probably
exceeding all interstate speed limits by this time!
RACE
Torque unity is at ~5980 with a 4th gear drop to ~4720 revs.

=4>5=
DAY-2-DAY
HAH -- how FAST do you wanna go? We know ~2700 gets us 60 mph in 5th and my TT likes to cruise @ 80 mph under 3500
RPM. Using the numbers, that conservative shift occurs at ~3350 RPM with a drop to 2700 in 5th, and a torque loss of ~35.5 lbs.
FUN
Shucks, we're going pretty FAST already, so I've been experimenting with around 5K, which should result in an RPM drop to
~4050 in 5th and a torque loss of 23.5 lbs. Hey, make sure your radar detector's doing its job here!
RACE
I do not know, but imagine 130 fuel cut-off might happen before torque unity is achieved at ~5920 RPMs in 4th, where RPMs
should drop to ~4800 in 5th. I do know I got 115 mph in 5th the other day and was only a little over 5K -- and felt very safe!

Sorry for being so long-winded, but am interested to hear from others on this, since it IS science combined with art! Hoping others
in warmer climates can provide feedback, since I'm battling too many cops and too much snow here...

Chris answers: "Had my 225 fitted with the Revo mapping; made big difference in the passing capability. Shocked a 911 and WRX on passing. Even better if you use the high octane gas. Petrol consumption improved as well." - 2/1/2005

Larkin adds: "Also look into apr tuning at goapr.com, they make great quality Audi, VW, and Porsche tuning products, even an upgraded turbo kit good for 360 some odd horsepower for under seven grand (talk about a sleeper) - 2/8/2006

Nathan ads "My TT 2001 is 225hp I got revo on my tt. Made a BIG difference on power all the way around. I checked up on other people chipping but revo plugs into your computer and reprograms it. You can't scan it so no dealer will no. it also changes your rpm to tap 7200. I got remus cat-back and Air-box. mine puts down 301 at the wheels and 310trq. In the 1/8 mile mine does 8.5 at 87mph. Revo all the way." - 5/22/2006

TTGuys adds "I also have it, and the feature I like is the heaps of torque, sometime when I am cruising on the highway, and want to accelerate, which I do, and then want to change from 5th gear to 6th, and realize I was in 6th gear already. I almost never use max HP, but love the torque." 2/22/2005
