I had deleted my 2012 Cummins way back when with an H&S and really liked that keeping it plugged in it acted as a gauge display and a diagnostic scanner.

From what I read the RaceME Tuner was good but the MM3 is better being basically a race me tuner with custom tunes specifically for your truck.

Question is if I choose to go with the MM3 and keep it plugged in on a mount will it too acts as a gauge display, and a diagnostic scanner?

It will clear DTC and monitor all the temps and pressures in real time?

Also will it all you to set maximums on temps and pressures so if you hit those it will alarm or defuel the truck to keep you from blowing things up?

Appreciate the input.

Going to delete soon and was curious about the live/real time features of the MM3.
