Give Your Truck The Power It Needs For The Weekend Haul

If you use your 2016 Duramax to tow toys, tools, or equipment and want smoother power without overdoing it, the Light Tow Tune from DuramaxTuner.com is a perfect fit. It wakes the truck up just enough to make towing easier, safer, and more enjoyable, all while keeping your emissions equipment fully intact. With an extra +55 rear-wheel horsepower and +99 ft-lbs of torque, you’ll feel the added grunt when pulling trailers under 8,000 lbs, whether it's a UTV, a small boat, or a loaded landscape trailer. Throttle response becomes more predictable, and backing up with a trailer is smoother thanks to refined pedal sensitivity and better low-speed control. What makes this tune so great is that it doesn’t try to turn your daily driver into a race truck, it simply gives you the power you should have had from the start. The truck still feels like your truck, just sharper, more capable, and more responsive when it matters. And with custom tuning from a team that actually answers the phone, you’re never left figuring things out alone.

A Smart Calibration Designed For Light Duty Towing

This Light Tow Tune is built specifically for 2016 GM 2500HD and 3500HD trucks running the 6.6L LML Duramax and using EFI Live SPADE tuning hardware. It's designed to enhance towing under 8,000 lbs without compromising emissions compliance or reliability. With more than 100 changes to the stock calibration, this custom tune balances extra power with safe, consistent engine behavior. SMART EGT Control is built in to automatically manage exhaust temperatures during heavy pulls, while revised air-fuel ratio limits help reduce soot output compared to traditional box programmers. The tune retains full factory turbo brake functionality and improves throttle mapping for better low-speed trailer handling, which is especially noticeable when backing up or maneuvering in tight spots. No wiring or sensor modifications are required, everything is handled cleanly through the OBD port with the EFI Live AutoCal V3 device. For the best results, especially on trucks with larger tires or drivetrain changes, pairing this tune with recommended TCM tuning helps maintain ideal shift patterns and drivability.
