any of those gas savers work for anyone on here?

A vacuum gauge offers instantaeous input to your driving.

If clearance allows, I would like to see someone try the Airaid 4 bbl carb spacer. They have documented improvments on carb and throttle body injection systems. The ridges in the spacer helps to break up the fuel that is running off the throttle blades, for better atomization. I realize the naysayers are going to have their input, but logic says that our with carbs or throttle body setups, the fuel (particularly at NON wide open throttle) is hitting the throttle blades and (for lack of better terms) dripping off the throttle blade. Whatever that could be done to improve atomization at part thottle conditions should be of help.
