Make Light Towing Feel Easier And More Enjoyable

If you haul smaller trailers or seasonal toys and want your 6.7L Cummins to feel more alive, the DuramaxTuner Light Tow Tune is a great fit. It gives the truck a noticeable boost in everyday performance without creating the stress that heavy towing tunes are built to handle. With an extra 40 rear wheel horsepower and 72 ft-lbs of torque, the truck gets up to speed more confidently, which makes merging and cruising with a light load feel smoother than stock. The revised throttle response helps the truck move naturally at low speeds, so backing up a boat or utility trailer feels controlled instead of jumpy. What makes this tune so appealing is how well it balances fun and practicality, keeping the power curve smooth enough for daily driving while still offering real gains when towing under 8,000 pounds. The factory turbo brake continues to work as expected, giving you downhill confidence whether you're towing or driving empty. It is a dependable option for anyone who wants their truck to feel stronger without sacrificing reliability.

Calibrated Performance For Light Duty Towing Needs

The DT1205010105000 Light Tow Tune is designed specifically for 2013-2017 RAM 2500 and 3500 trucks equipped with the 6.7L Cummins, pairing custom engine calibration with the EFI Live AutoCal V3 hardware. DuramaxTuner built this file using more than 100 changes from stock, optimizing fueling, boost control, pedal sensitivity, and air to fuel ratios. SMART EGT management is integrated into the tune, allowing the system to automatically adjust fueling to keep exhaust temperatures under control while towing. This makes it ideal for small boats, UTV trailers, work equipment, or any load below 8,000 pounds that needs predictable and efficient power. The tune limits soot production and improves overall engine cleanliness compared to traditional box tuners, which helps maintain long term reliability. For trucks equipped with the 68RFE transmission, pairing the tune with transmission calibration offers smoother shift points, better line pressure control, and improved torque converter behavior under load. Manual transmission and Aisin equipped trucks are supported for engine tuning as well, ensuring a consistent improvement in drivability regardless of configuration.
