Towing Small Loads Has Never Felt This Good

If your RAM 6.7L Cummins works hard during the week and pulls light loads on the weekend, the Light Tow Tune from DuramaxTuner is exactly what your truck needs. It gives you a noticeable bump in power, about 40 rear-wheel horsepower and 72 foot-pounds of torque, without sacrificing the drivability you rely on every day. Whether you're hauling a UTV, a small boat, or a few pieces of equipment, this tune keeps your power delivery smooth and your engine temperatures in check. The throttle feels more responsive without being touchy, which is especially helpful during low-speed trailer maneuvering or backing into tight spots. You’ll still retain full functionality of your turbo brake, which adds confidence when towing downhill. With cleaner power and reduced soot compared to box programmers, this tune is built to work smarter, not harder. If you want your truck to feel lighter, quicker, and more responsive while still handling light towing duties with ease, this tune hits the sweet spot.

Calibrated For Control When It Matters Most

The Light Tow Tune is a fully custom calibration designed specifically for 2013-2017 RAM 2500 and 3500 trucks equipped with the 6.7L Cummins. It’s emissions intact, meaning your factory emissions system stays in place while still delivering a healthy boost in performance. Built with over 100 changes from stock, the tune refines air-fuel ratios, torque management, throttle sensitivity, and turbo control for a safer and more capable towing experience. SMART EGT control is integrated to automatically manage exhaust gas temperatures, helping protect your engine when pulling up long grades or in warmer conditions. For drivers running the 68RFE automatic, pairing this with transmission tuning unlocks better shift points, added clutch holding, and more confident power delivery. Manual and Aisin-equipped trucks still benefit from improved pedal feel, low-end torque, and optimized fueling without overloading factory components. This is a true light-duty towing tune that balances power, control, and longevity for everyday use and seasonal hauls alike.
