I have a Banks Automind programmer. The model is 66412. It works for many models and years. It has 4 different programs all for an emissions intact vehicle. I used the work/tow tune and noticed better power, shifting and mileage. It works as a code reader as well. I bought a new truck and it’s no longer compatible. I had it on a 2010 Cummins. As previously stated it works for many models. From the banks website it will work for 2004-2012 ram 2500 with Cummins. Please pm me for more info and pics. Asking $250.00 for the unit. Have original box and all cables and instructions.
