MM3 VS MM2

[Schultz-ee]

New to the page and Cummins in general. Bought a 2012 recently and it has a tuner on it, deleted but still has the equipment on the truck (going to be fully deleting soon) curious on the MM2 or MM3 for STRICTLY a gage monitor for the time being. Is one better then the other? Would like some advice before I spend the money.

There is no more support for the mm2 that i know of so i would be MM3 if they were the only 2 options… if you want gauges get the edge CTS2 they are far superior
