i was wondering how much hp i would gain and how much i would feel with the afx t/b......also on ptunin's website it says 56mm t/b but on howell and the others it says 55??????did ptuning just mess up or what....
as far as mods go i have a cai, muffler, ngk plugs and wires.....should i expect any noticable gain from the t/b?

you'll like it. back in my N/A days, it was probably the best peformance mod i did. exhaust was pretty fake. just made my car a little louder. i should have just gotten a GS-T cat-back. UDP was nice too. putting a K&N at the end of the stock intake was ok i guess, but i noticed the greatest gain from the AF/X throttle body.
