Never seen so many comments in one thread in one day? ; P

I also guess I will be killed if I say anything good about CAI.

CAI, boost controller and header will improve drivibility, but not much gain on power. Up to urself

choose the right tuner, a bad one can waste all the money u spend on mads, and cause harm even. If u do get CAI, make sure tuner will bother to scale the maf probably ; P
