I'm reving this thread as i cannot find much on the subject despite a long search.

I have a friend with a Ford Focus. His Forum/Club (yeah, they have one) has found that grounding the Throttle body to the Battery Neg post does much the same thing as a sprint booster.

One poster actually claimed a Dyno proven 3 HP at the wheel increase. I kinda doubt that but better throttle response would be a good thing in itself.

Has anyone tried this? Any possible damage?

Ideas?
