I could tell the difference as soon as I left the driveway. Like driving a totally different truck. So far no difference in fuel consumption. Truck smoothly running on all 8 all the time. Fantastic acceleration and tranny shifting super smooth through all 6 gears. Love it! No battery problems whatsoever. Somewhat on the pricey side but quality device. No complaints at all. If you hate AFM your gonna love this little guy!
