Performance chip installation is one of the perks of diesel truck ownership. At Flagstaff Transmission Specialists in Flagstaff, AZ, our mechanics can professionally tune and install a chip for any application, whether you drive a Cummins, Powerstroke, Duramax, or otherwise.

Performance chips are widely popular, and it’s easy to see why. By altering parameters within your truck’s electronics, a chip can provide a boost in horsepower, increase torque, alter efficiency, and even affect your engine’s sound. Typically, installations are simple, and totally reversible; meaning you don’t need to worry about affecting your truck’s resale value or permanently committing to an upgrade. Chips are one of the simplest and most effective ways to get the most out of your truck, whether it’s for off-road use, hauling, street driving, or all three.
