Fast shipping. Excellent value. Only issue I had was having to update the programmer new out of the box? Otherwise easy install. Using the econ setting so I don't necessarily feel a performance gain but hoping for better fuel mileage. Only programmer I use is Hypertech.
Different Tires? You need this! Ram 2500 Cummins, it's a must

So, 2014 Rams, the dealer can only program stock tire sizes. Puttin 35s or bigger on your Cummins? GET THIS NOW! Your truck will drive 100% better. My speedo is accurate within 0.5 MPH @ 75 MPH...amazing.
