Some are cutting the gas pedal and re-welding it to get full throttle and others are taking a 5/8 I D heater hose and sliding it over the pin that the throttle cable rides on. This pin is located at the top of the gas pedal and underneath it. You can check full throttle by pulling of the air supply line from filter to engine and look and see if throttle is wide open or not when you puxh all the way down on pedal.I don't know if this was really a problem, but just another way to get all you can get.
