Take Full Control Of Your Truck With Just A Switch

There’s nothing more satisfying than having the right amount of power exactly when you need it, and with Switch-On-The-Fly tuning, that’s exactly what you get.

And when someone else is behind the wheel or you’re troubleshooting a mechanical issue, drop it into Optimized Stock for safe and stable driving. It’s power when you want it, safety when you need it, and drivability that makes your truck feel better than ever. This setup is perfect for the truck owner who needs versatility without compromise.

Precision Calibrations Built For Real World Duramax Drivers

Each of the five included tunes, Optimized Stock, Heavy Tow, Light Tow, Street, and Sport, are handcrafted with more than 100 calibration changes to deliver refined performance tailored to your needs. Designed to work with your emissions equipment intact, this 49 State Legal tuning package gives you cleaner power and smoother shifts with no wire hacking or unnecessary guesswork. SMART EGT control automatically manages exhaust temps, while built-in air-fuel ratio limits help cut down on soot without sacrificing power. The Heavy Tow tune gives you steady power when pulling up to GVW, while Light Tow and Street bring fun drivability and low-speed control with smoother pedal sensitivity. For all-out acceleration, the Sport tune transforms your truck with 532 horsepower and over 1000 ft-lbs of torque at the crank. This kit also includes the EFILive AutoCal v3, making it easy to flash updates, log data, and fine-tune diagnostics. With proven reliability and unmatched support, this is tuning done the right way.
