Hello everyone, I bought an MM3 Power blank tuner for 2019-22 RAM Cummins from DRD.

It's still in the box and brand new; I haven't hooked it up.

I'm looking to get $900 for it.

If you're interested, let me know. You can contact me via email at jjl@elmwoodcdjr.com or Private message.

I will send pictures if needed.

I'm only selling because I sold the truck at the last minute.
