i wonder if your rev hang is "board" issue..could also be a worn out spring for that matter as the spring is the only thing that brings the butterfly shut

Hello Short,

Are you running a 1zz? I am thinking of doing this mod.

I am wondering how the 1zz effects fuel efficiency and if the torque is increased? If it helps my car up hills without too much of a fuel use penalty I wish to give it a shot.
