What voltage is the throttle position sensor supposed to be set at? Do you increase voltage to richen or lean out the fuel mixture? We were talking with a guy at a a local bike night at Quaker Steak and he mentioned about adjusting the throttle position senor to give a little more performance similar to what the mustang guys do. Our daughter is saying her exhaust is really hot. I was thinking about tweaking the throttle position sensor to see if it would help before she buys a programmer. What are your thoughts?
