i cant seem to find any online, i want to trade my M3 in on the S4, but i cant seem to find any tuning companies and its making the deal sour to me. part of the reason i love my M3 so much is that there are tons of aftermarket mods i can do to it, and i think the V8 in the S4 can be made into a monster, but i cant find anywhere to buy aftermarket parts.

could you guys give me some links to them?

There is an exhaust worth 5-10 and a speed limiter delete from Dahlback, but they are x pensive and there is nothing more at this time. Altho, I think if you just put some good old hot rod engineering into it, headers, higher comp., bigger valves and improved intake tract you shoulld find 50 or so more if you can persuade a tuner to do a chip to the new parameters. It could be done but would cost a lot. I heard their were probs with the superchargers that have been tried. A rs6 engine could always be made to fit and with the right tranny it would fly, but it would be a project costing more than you would pay for the car.
