More importantly, how does it sound!?
The gains seem modest but that could be the dyno, conditions. There are many posts with stock, then CAI, headers, tune overlay around here. I had the manual transmission for results below so keep that in mind.
1) Roto-Fab CAI
2) Kooks 6511-complete (1 7/8" LTH, catted x-pipe, mufflers)
3) Tune by R.P.M. Motorsports (Garner, NC)
