I have a like new MM3 tuner for sale.
Comes with all the original equipment.
You must purchase a VIN license and custom tunes for your truck!
I am looking to get $650 OBO, but I am unsure what shipping will cost you as I’m in Texas.
I purchased this for my 2018 RAM and was holding on to it till the warranty ran out.
I got rid of the truck in 2020 and just now found this in my closet.
