I don't think I've ever had lift kick in that early, but it could very well do so on later models w/ the lower rev limit.
Does lift feel just as strong as it has before? How many miles does your car have on it, and what year? Sounds like it might be time to replace lift bolts.
As for the low end bogging and the CEL, thats definitely from the CAI
, you are most likely burning lean. There is a mod somewhere on this board that fixes it, but I think you have to cut the CAI
pipe and replace with the smaller stock Intake
tube, right by the throttle body.
