There are alot of other mods that make alot better hp/$$ ...... I dont think that a Fast setup is worth the money for as small of gains you recieve.
Look into a cam, heads, ls6 intake, ported TB, full exhaust.... with the right setup you can make some kickass power for a very reasonable price

Remember that you should start saving for a new trans and rearend! The stock stuff is WEAK!
Use the search..... you'll be reading forever.... Make sure you do ALOT of research then decide on the setup thats best for you!
Was going to install tomorrow. But i had my wisdom teeth extraced today. Still bleeding like a stuck hog and flying high as a kity ( pain pills ) looks as it it will be next weekend.

what is your car? year/make/model/A4 or M6
