DFM disabler released

I would say there is an improvement in acceleration and transmission smoothness, or at least not having the engine hunting and turning cyclinders back on during tip in throttle and acceleration. This then equates to less or no transmission hunting as well.

THIS is what I'd expect.

Big difference between not firing the fuel injectors on decel (which is a good thing) and telling the lifters to collapse and not open the valves, which is what DFM does that the Range Tech device leaves on.
