Driving with the AFM Disabler made a world of a difference. No more awkward hesitations or shuddering shifts as the engine toggled between V4 and V8 modes.

After a few trips, averaging about 18 mpg on a longer drive, we couldn’t help but wish we’d made the switch sooner.While we hadn’t expected to see drastic changes in fuel economy right off the bat, we did appreciate how the device maintained engine performance without forcing us into that irritating V4 mode.
