Great, my Harbor Freight vacuum gauge will pay for itself. "Set it up in reverse and you have a time machine." HAHAHAHAHA. Good one.
Most of this stuff is gimmick unless they can guarantee or money back on a big increase. I really haven't seen too much that would really help milage besides tune ups, headers, weight, etc. Some guys say the tornatos work and some guys say they don't...
I'm building a gas milage 83 4x4 so open to suggestions like these.
