Best chip or tuner for mileage gain? Imput please
Most of the aftermarket enhancements will give you a minimum of 10%. I here reports of some unreal mileage gains. Most of which are BS. I only believe what I can document. My 2004 gained 3 mpg highway on the Performance setting of my Bully Dog Triple Dog.- ranchrodstx
