Hello everyone!

I'm a new member myself and forgive me I'm not too savvy with how things work so please be patient LOL.

I also had a few trucks all Cummins, but I just purchased a beauty over the weekend! 17' Ram 2500 Laramie.

This truck come with a MM3 tuner, which from what little research I've done I might not be able to do anything with....

Any and all advise would be appreciated!

To sum it up I have no idea when it comes to how to get going /proceed.

I was told by the dealer it's back to stock?
