Hey yo what's up? I have an 06 m6...i love the performance of this machine straight out of the dealership dont get me wrong. just looking to put down a real 400 ponies to the ground if not a little more with modifications that won't put any more dents in my wallet. can anyone tell me any tricks that would help me out. i've heard from a few people that i should be putting down somewhere between 360 and 390 hp bone stock...is this right or close or whatever? i plan on ordering the k&n CAI but have no idea what else to pick up. i don't really want to mess with the exhaust right now. i know there has to be some other less expensive ways to get power. please help me out so i can be one of the very few guys running around my parts in the 400 RWHP club!!! thanks a bunch.
