What CAI did you purchase and is it tuned? also how did you determine your car is slower?

Wht JJ said, some CAI's need a tune to run correctly. A tune really wakes up these 3.7's and I suggest MPT..best one for the 3.7

Cool loss power

K&N Series 69 Typhoon Cold Air Intake and Pypes Mid Muffler Cat-Back Exhaust. I pushed the car with my stock intake and I can feel some power, now the car sound sgrat but is like a heavy cow. if I need a tune, is good to buy on of those devices that tune your car or is better to go to a shop.

I was reading about BAMA tune but just what people say about the money.

For the 3.7, you want to skip Bama and go with MPT..much better tune for the 3.7...just get the SCT X4..you will love the difference. If you hve an auto, make sure to get the trans tuning with it..shift points are awesome.

I have a 2011 mustang v6, and it happens to me every now and again......from a stand still, or if I am doing a rolling stop, i will push the gas and for a split second it hessitates, then kicks in
