For sale is a hardly-ever-used MM3 tuner.
I used 1 VIN License.
It was never installed in the truck.
I only used it to take a stock read.
Comes with all cables and the suction cup window mount.
Not sure if you have to purchase an unlock or another VIN License.
New is $850.
I am looking for $525 Shipped to the lower 48.
