A4 2.8 chip
GIAC seems to be preferred though.
I don't believe you can chip a 2001 or >.
If you go into the dealer, you have to swap em. But most dealers don't trip, as long as they are somewhat mod friendly.
If you chip, go K&N, and get an exhaust system like Milltek, you'll probably only get 30 or 40 extra hp. If you've got cash to burn... Get the PES Supercharger, with their chip. That's the chip I want.
