Throttle Body Spacer on New GM truck?
Has anyone with a new GM truck w/ 5.3L V8 tried one of those throttle body spacers? If so, was it worth it? I'm hot looking for h.p, looking for better fuel mileage.

A TB Spacer is a waste of money unless you are going to run nitrus. If you want fuel economy spend you money on a CAI, LT Headers with duals and a Custom Tune from someone like Nelson Performance. These are the most cost effective mods for both fuel economy and hp gains at the same time. I would also suggest E-Fans and an underdrive crank pulley.Chris S.
