Anyone out there have any suggestions on the next step to more power? I have an 07.5 duramax with ppe hot+2 ,4"mbrp turbo back exhaust,air raid intake,and ported fuel rail fitting.It dynoed with 479hp and 830 ft lbs. to the ground. I know trans work is next thing to come but want more power after that.....
