I have been running 33" tires instead of the stock 31" for the past year, and the shifting of the transmission was just not right in terms of shift points. I knew that with my plans to switch to 35" tires in the very near future would further amplify the issues with the shifting as well as traction control. So I bought this device to bring everything back within spec. It really did work well. I look forward to using it again next week when the 35's are mounted.
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.
