I recently bought my first Cummins, it's a 2013 2500.
It was fully deleted (best I can tell anyway) when I bought it.
I noticed that it had a cable running up to the dash where a screen used to plug into after following it down I learned the was a MM3 box under the dash.
So I contacted MM3 and ordered a new screen but now my problem is the only tune I have is whatever tune was on the truck when they took the original screen.
Is there anyway I can figure out who tuned the original screen and contact them about buying another copy of the tune or am I just gonna have to abandon the tune I have and get new ones?
Thanks for any help.
