best for power
im doing a pi swap for my 98 gt. everyone talks about bolts on being a wast of money. i only want mods that creat good power gains so besides a pi swap what else should i do besides bolt ons. i already have a cat back and gears and dont want to waste any money. im going to do a bbk o/r h pipe. any suggestions besides a blower or nitrous
