I realize that the lower RPM's by themselves won't help much with milage, but combined with EFI it will. As it is right now, to go the speed limit of 75 (outside the metro area), I am turning over 3,000. I see no need for that if I can avoid it.

And the EFI I am referring to is a converted GM TBI system I have. Let the beatings begin.
