20 mpg is real good. does the throttle body spacer actually do anything? I hear so many mixed reviews I want to get one but i don't know if it's worth the money. Someone said that if I want to not spend much money to go somewhere and have like a machinist make me one or something. What's the best 3 gas mods you recommend from your experience with your 4.7? I have a 2004 Ram 1500 4.7L 5mt it's lightly modded. The only two gas saving mods are a magnaflow catback dual rear exit and truxport tonneau.
