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.
