Change out the throttle body question
Does anyone know if the throttle body is changed out to a "JET" component will create a noticeable change to the performance? I have a 2011 GMC SWB truck with a 5.3 and a 6 speed auto. I have the engine EFI Live tuned and the intake and exhaust changed over to more efficient systems. I am curious if a JET throttle body will open it up more. The info on their web page states the response is quicker. Is it worth the amount of investment in the throttle body component?
