I will also agree with AMChrisRose. I just recieved my airaid cai, and BAMA tune. I went with the 91 octane race tune. And the car is totally different from stock. It is a monster. and that is with 3:31 gears. I bought 3:73 gears, but don't have them in yet. I am however, going to call AM and have them upgrade my 91 octane tune to a 93 octane tune. But, I have no complaints what so ever. Way to go AM BAMA tuning.
