when it is at WOT is the butterfly inside the throttle body supposed to be all the way opened? from what ive seen when looking at mine it is not even coming close to that, is this right?
Well you really don't want any restriction to air flow through the motor.
In a nutshell, that is what mods to the motor is all about, more air flowing through the motor. A little extra fuel to go along with that improved air flow is always a good thing also.
