For the VQ35 guys, if you add headers and all the bolt on goodies then tune properly; there are basically ZERO cars that will have faster throttles. Not an E46 M3, not an E39M5, NOTHING. Dont waste your time doing this mod.

This is the LAST thread on this subject Im going to allow. and unless one of you makes a miraculous discovery, this topic has been more than covered.
