[QUOTE="GodStang, post: 15813187, member: 11142"] It can actually be bad. We did porting on a lower. Dynoed the car. Pulled the lower while sitting on the dyno and put the new ported lower on and redynoed. Gained no hp and lost no boost. Same car, same dyno, same day, only change was a lower intake. If you port match the lower intake to the gasket and DON'T have ported heads you have just put a decent size lip in air flow path that can/will cause turbulence and can actually make the flow worse.
