    My truck used to belong to ryder and when I got it, it maxed out at 74mph. But it was also password protected. Cummins flashed it.

    Easy fix, the dealer or anyone with the correct software can contact Cummins and purchase a ZAP IT password. It may cost you $100-200 plus what ever the tech or dealer charges. This will eliminate the MPH restriction and allow you to change it to your liking.
