No, I didnt have a bad experience, just throwing my 2 cents in. I did some research into this in the past, and concluded it will not affect your performance as long as its not causing any problems in the first place. The computer reads the voltage from closed throttle to wide open throttle as a reference for throttle position, and the voltage itself is meaningless as far as increasing performance by tweaking it .1 or .2 volts one way or another. I guess Im just tired of this misconception, didnt mean to sound like a prick, and who knows, I could be wrong.
