Damn! When do you sleep?
I'm not the expert on how the chips do their magic and I think most of their claims are absurd. In my case, I drove my car for months before I got it chipped. I think I told you earlier that I drove stock and modified cars back to back before I had my car done. After the modification was completed, there was a noticeable difference in my car. Not quite day and night, but enough of an improvement to get my attention. I haven't really noticed a significant change in driveability, but the fuel economy dropped about 1 mpg or so. The turbo definitely kicks in much harder. It could be that this chip optimizes the performance aspects, but trades off the fuel economy. It's all in the software.
Speaking of trade-offs and the TT: think about who the TT targets. I think you have said before that the TT is more of a luxury GT than an all-out performance car. It costs about 43K, so it probably caters to an older, affluent clientele. So, it might not be wrong to assume that any compromises would be made in favor of luxury and smoothness versus screaming performance. I think that Audi probably left alot of performance on the drawing board for this reason. That's what makes it a ripe target for aftermarket improvements. A car like the S2000 has a different target audience. Most S2000 drivers are looking for exceptionally strong performance, so Honda probably wrung as much power out of it as it could--nobody builds better high performance engines. Therefore, because the S2000 suffers from fewer compromises, it would be much tougher to improve upon.
Another factor that makes the TT a better candidate for improvement through chipping is the turbocharger. One of the easiest performance mods on modern cars is to crank up the boost. The TT's boost is set rather conservatively because its target audience probably would be less tolerant of that kick in the back you get from a high boost turbo. A car like the S2000 has no equivalent "easy" modification becaue it doesn't suffer from the same weakness.
The boost issue calls to mind your point about durability. The stress of a high boost turbo is bound to have a negative effect on longevity. Personally, I'm not concerned about engine life because I don't keep my cars long enough for it to be a factor. As long as it doesn't blow up during the two years I'll be driving it, I don't care. I'm sure that Audi cares because they're responsible for warranty repairs.
I guess what I'm really trying to say is that auto manufacturers must make compromises to make their cars attractive to the widest possible audience, but they do target specific market segments. My TT suffers from compromises that make it slower than it should be. The chip corrected some of the resulting deficiencies.
Perhaps the best proof of this concept is the changes Volkswagen made to the Jetta 1.8T between the 2001 and 2002 models. They altered the software to increase turbo boost and gained 30hp!. (180 vs. 150) That's essentially the same thing chip makers offer to the rest of us.
By the way, I hope I didn't offend you--that wasn't my intent.
#272 of 512 RE: habitat1 SHORT ANSWER

In case you don't have time for my rambling diatribe above, the simple answer is TURBO BOOST. I would be as skeptical as you about claims for non-turbo, high performance cars like your S2000. However, for a turbocharged car like the TT, turning up the boost (via a chip) results in turning up the fun factor. As you suggested, it also increases the likelihood of engine failure.

If I do chip my 180TT, and drive it sensibly, what are my chances of engine failure? The guy who was going to do it said that I would have to really beat it up for any engine damage. He also said that I do not need a turbo timer. Any comments would be deeply appreciated.

Do I need to change them to all season? If so, how will the all season differ from the performance?

No previous offense was taken and I greatly appreciate your response. I hadn't considered that the fact that the TT was turbocharged added another (significant) factor that could be reprogrammed by chipping.
We have three TT's residing within two or three blocks in our neighborhood and another interesting factor is that they are all "daily drivers" (i.e. they are all the second car in a husband/wife household). Two of the three couples are recent empty nesters. Our S2000 is a third car and although I drive it almost daily, from a practical standpoint we cannot afford to give up my sedan or my wife's SUV. Perhaps that's also one of the trade offs. With it's added luxury, less "hard edge" performance orientation and front or all wheel drive, the TT is a bit more versitile than the S2000.
Thanks again for the response and best wishes.

Huma1: Sorry for ignoring you! Audi TT's are some of the best used car values around. They are well made cars with excellent warranties and FREE maintenance. So, the car has probably been taken care of pretty well. I'd be more concerned with a car like a Porsche Boxster--it's a great car, but costs a lot to maintain.
Without knowing all the options, it's tough to get a true value on the car. However, assuming that it has the performance package and the xenon lights, Edmunds puts the value at: $21,749 (trade-in); $23,693 (private party); and $25,623 (dealer retail). Considering the fact that it will need tires soon ($1,000+), I 'd say $26,700 is alot to ask.
Are you buying it from an Audi dealer? If so, is it "Audi Assured"? That program extends the warranty to 60 months and 75,000 miles (it adds about $1,000 to the value).
You might want to take a look at E-Bay to see what cars sold there for recently. Don't even consider what the Black Book or Kelly Blue Book tell you for values--they are written BY the dealers FOR the dealers.
Finally, I would take the VIN number to the local Audi dealer and check the car's history. Because of the free maintenance, the history should be fairly complete (no repairs done by the local auto hobby shop). If you're really nice to the sevice rep, he might give you the original owner's name so you can talk to him.
#280 of 512 Performance/All-season tires
Jul 12, 2002 (7:50 am)
You didn't say if you live in an area that has a a true winter, i.e. snow, or not. Performance/summer tires will not work in snow/ice conditions. I live in the Cleveland area and opted to go with winter tires mounted on a second set of wheels. This not only gives me added confidence it also saves the shiny stock wheels. All seasons would of worked but since I was wanting to change the set for winter why not go for the real thing. This part I'm not sure of but it would make sense. I don't believe that the compound of the performance tire will respond as well in colder conditions which would be another reason to change over to an all season tire. The tire rack tirerack.com has a great selection of tires and wheels for the TT. Hope I've helped.
