not sure but when you go to the place to get it flashed they will tell you exactly which programs they have for your car

I have a sport and no red t... I want one damnit!

Anyway, I think the red T means something else (hp related). Read this:
http://www.audiworld.com/news/02/102402/content.shtml

the red t has nothing to do with sport. it just mean u have a the 170 hp 1.8 instead of the 150 hp one. its on 01 and newer. heres a thread talking bout it https://www.audiforums.com/m_138811/tm.htm

okay so i talked to a helpful guy in colorado about chipping, they use giac and claim 187hp from a b5 a4 1.8t, does anyone know why an APR chip will be better?? differences?? and where can i buy a better/aftermarket DV

Would anybody happen to know if the GIAC chips extend the redline or remove any speed limitations?

I thought I read something saying that they did, but I looked all over their site and didn't find anything about it...

i think they raise the rev lim to 7100 and remove the governor

On a 1.8t, right?

What about on a 2.8 30v?

What exactly does a chip do?

a chip will remap your fueling and timing to match the increase in boost that it offers.

You can raise the speed limiter to virtually remove it through Lemmiwinks.
