Underdrives have caused issues with the Mach, do a search. They aren't worth the money.

Full exhaust
Intake - port and polish it, throttle body and head side
Throttle body - either polish and port match factory to the intake or get an Accufab

CAI and RAI are over rated - it's the tune that does the hp increase, not the CAI/RAI. Save your money here. Stay factory and leave the screen in, it's there for a reason.

Intake spacer - small gains

NA power - do cams
Real power - put a blower on it but be careful with the stock bottom end.
