    what year is it? if it is an 05 or newer, its drive by wire which means it has a computer controlling the flapper, so the best way is a custom tune

    yeah it will help, but the biggest hold back is the computer controlling the throttle, just because you foot is on the floor doesn't mean that the flapper is fully opened

    Alot of trucks have electronic throttles, like my truck has the option, when i was installing my throttle body spacer it was talking about there being a possible electronic throttle.
