    Question Reprogram computer for bigger fuel tank

    I was looking at getting a 50-55 Gal tank upgrade for my truck from the standard 32, Is there any way to reprogram the Distance To Empty within the computer. typically you'd get 450-500 miles to empty with the stock truck depending on driving conditions, with the new one you'd be at around 1000 miles to empty, Does the MM3 have this capability. Im currently waiting for the 2020 Ram 6.7 to be available to order, from what i've seen on the 19's you cant even take it into the dealer to reprogram.

    I'd like to hear this. My main when capped is 61 gallons and the trucks lie-o-meter is the only thing I have and can't be changed. Not really important, but nice to have.

    Might want to look into either an Autel or the AlfaOBD.

    Can't speak to anything about the 19s or 20s and their reprogramming capability; but that seems like something that should be fairly easy to adjust.
