Engineered Tuning That Puts Performance In Your Hands

DuramaxTuner’s Switch-On-The-Fly tuning kit is more than just a power boost, it’s a fully engineered calibration package designed to maximize the 6.7L Cummins potential while preserving reliability. Using EFI Live and the included SPADE handheld device, this kit reprograms more than 100 parameters within the truck’s ECM for optimized fuel delivery, torque management, EGT control, and throttle response. Each of the five tunes is tailored for specific use cases, from a mild optimized stock setting to a high-performance sport tune that delivers an additional 100 rear wheel horsepower and 180 foot-pounds of torque. Towing tunes include SMART EGT management and air-fuel ratio safeguards to keep temps and soot under control, even when hauling near GVW. The system also retains full functionality of the factory turbo brake and avoids the need for cutting into factory wiring or tricking sensors. Transmission tuning for the 68RFE is also available, adding improved shift strategies and torque converter control. For Cummins trucks equipped with the Aisin or G56 transmissions, the tuning is specifically adapted to match those drivetrains, ensuring a seamless and efficient upgrade.
