So my question is; are there mods we can implement to the XR that IMRPOVE mpg? Like a chip that we can toggle between an HP reflash and an MPG setting? I searched but didn't see any posts. I don't want a XR-Prius, I want to get better MPG until I want the HP and torque. So no on smaller injectors. I've heard you guys saying that driving under easy throttle with a S/C has improved MPG. What else is out there? Products? Ideas? Experience?
