hello i have an auto 2012 mustang gt. and i want to to get the actual 412 hp. since the parasitic loss brings it to around 370 if im lucky. so my question is should i get an aftermarket air intake with a tune or should i get ford themselves to tune it because im worried about wording the warranty.... please help

If you run 91 or 93 octane in it then you are probably getting better than 412 HP. The factory rating is at the flywheel, the 370 you are looking at is at the rear wheels.

A CAI and tune probably won't get you to 412 at the wheels, add a cat-back and it might.

I'm at 400 rwhp with a BBR DYNO tune, Steeda CAI. I go the Borla ATAK axel backs for sound. SUGGESTION.......... get a dyno tune NOT a mail order tune.
