I just purchased a MM3 tuner for my 2010 ram 2500. Cummins 6.7 obviously. LOL.
It's been deleted for a very long time.
I am currently running an H&S mini Maxx tuner for the engine as well as the overdrive transmission tune.
I have done a pressure mod to the transmission (something with accumulator plate, drilling a small hole and adding a bb/bearing to a hole.
This mod was supposed to allow higher line pressures.). The whole setup works great but it's very lacking.
My question is... Do I need to return the ECM to stock with the H&S before I re-tune with the MM3?
Also, my setup is very basic. 4" turbo back with a pass through muffler and factory resonator (it's quiet, just like I want it.) EGR delete.
Stock intake with k&n filter. No other engine mods. Stock transmission.
What settings would you all recommend while using the MM3?
Any advice will be appreciated.
