    A throttle body spacer got me 4 mph on mine I was told use a good one by a friend of mine, it even shifted better. I've bought three other ones for different trucks and have not seen anything. Kn I got nothingon that truck until we did the whole intake that brought air from outside, under hood to much heat.
