Your foot controls the MPG. It is no way linked to the PCM or in any way a “tune”. It has over 40 settings, ECO, CITY, SPORT, SPORT+...in those settings you can adjust even more. I run SPORT at a +1 level. It makes the truck very responsive to pedal input. You still control the fuel flow so your SMILE affects the MPG.Does the PC help (or hurt) fuel efficiency at all? I haven’t even heard of this thing until I became active on this forum sight so just trying to research as much as I can.
If you line up 2 Identical Rams, one with PC and one stock...take out the human element factor, the PC truck will out accelerate the stocker everytime. It is like having a cheat for reaction time, so power comes quicker. When you are on the freeway and need to pass, it feels ALIVE, not waking up from a slumber...
