Cummins Diesel Parts & Ram Diesel Performance Parts

Here at Dr. PerformanceRx, we are all about unlocking the potential already contained inside your engine. Adding in our Cummins diesel parts or our Ram diesel performance parts amplifies the power that your truck was originally designed to have. Our chips are undetectable by the ECU, which means there’s no voided warranty to be concerned about, and they increase your truck’s ability to perform at its best capacity. Our chips are easy to install because of OEM factory connections; plus, they will increase your fuel mileage, help your engine run more efficiently, and reduce cylinder wash. Enjoy more power and torque from your Cummins or Ram truck once you install one of our modules.
