04 GTO LS1, SW LT's & K&N + my tune
Dyno'd yesterday -heres the best #'s. K&N, Stainless work LT's.
This is with cats, and stock cat back.
319.6HP/338.Trq
Bone Stock (back in feburary) was
299HP/326 Trq
I have to admit I was hoping for a bit more. AFR was right on 13:1, although it was bumpy in places. The loss in low end TRQ is bothersome too. I noticed that a while back when I put the K&N CAI on it. I think I may take it off and go back to the stock intake & MAF calibration.

Throw a diagnostic on there. Looks like some KR up top maybe? Check to make sure the exhaust is not touching anywhere to cause false Knock. Car should make around 330 RWHP properly tuned.
