We've used our own software package for the last several years to develop our own performance programs. With a properly built transmission and driveline, it's relatively simple to make your Duramax  truck faster than a Corvette! We've had dyno results of over 540 HP and 1080 ft/lbs on an independent dyno test with our computer upgrade alone and stock turbocharger.

See Programming Software Price List to view details on purchasing our system.
