While the bolt will keep the throttle from opening all the way, I thought that the accelerator pedal wouldn't be all the way to the floor and pushing it to hard may stretch the throttle cable. How do you keep that from happening? I also thought the etgenie may have been what I was looking for until I remembered I have two four barrels and $850.00 just to slow me down seems like alot. Anyone have any other ideas?
