I just put on a CAI. The only other mod that I have gotten to so far is a 2.5" dual Magnaflow exhaust. I was running in the low 16s (I live over a mile high), and now that I put on the CAI I am consistently running high 16s and 17s. I can feel more power through out my whole RPMs but I don't know why my times are so much slower? Any ideas??
