Built To Tow With Confidence Every Day

If your truck pulls double duty between work and towing, this Light Tow Tune is built to feel right at home. It wakes the truck up without turning it into something temperamental or hard to live with. Power comes on smooth and predictable, making it easier to get rolling with a trailer and stay relaxed in traffic. Throttle response feels more natural, so you are not constantly feathering the pedal at low speeds. Backing a trailer into a tight spot becomes calmer and more controlled, especially when maneuvering on uneven ground. You still keep full factory turbo braking, which makes long downhill grades far less stressful. Best of all, it delivers usable power where you actually need it, not just on a dyno sheet.

Smart Calibration Designed For Real World Towing

This Light Tow Tune focuses on efficiency, control, and long-term reliability while towing under 8,000 lbs. Custom SMART EGT control actively manages exhaust temperatures to help protect the engine during sustained loads. Air-fuel ratio limits are built into the calibration to reduce soot and keep emissions equipment operating as intended. Power gains of up to 55 RWHP and 99 ft-lbs are spread across a wide torque curve for better drivability. The factory turbo brake remains fully functional, maintaining safe downhill control. Revised pedal sensitivity improves low-speed trailer maneuvering without sacrificing highway comfort. With over 100 calibration changes from stock, this tune is carefully tailored to work seamlessly with your Duramax and EFI Live platform.
