Have 2016 2500.
I have done the supporting mods to handle the 200hp tune file.
When I start my truck and put it on the 200hp tune, it works GREAT.
When I shut the truck off and turn it back on, it acts like it has a Valet tune until I put it back to 200hp.
I have it set to send every cycle; I verified them before even considering asking for help.
I never noticed it before the mods, as I left it on the 60hp since I bought the MM3, but now that I want to play around.
I must re-elect the tune I want anytime I turn the truck off.
HELP!
