I have a 99 Ram 1500 5.2l, with the mods listed in my signiture. I've been reading up on some mods to get better mileage, and one of the recommended mods is the fast man TB... I also read that it seems trottle body spacers really don't do anything at all, and may even hurt performance, is that true? I have a PowerRaid spacer on my truck that came with it, so I never thought about taking it off, but I figured if I get a new TB should I ditch the spacer while I have everything apart? I freakin hate the whistle it makes, it always makes me think I have a vacuum leak, so if it does absolutely nothing for my power, or gas mileage I might as well take it off and sell it to recoup some of the cash for the TB... What do you guys think?
