The Perfect Middle Ground For Daily Driving And Light Towing Confidence

If your truck pulls double duty as a daily driver and a weekend workhorse, this Light Tow Tune is built with you in mind. Designed for the 2010-2012 RAM 2500 and 3500 6.7L Cummins, it adds up to 40 rear wheel horsepower and 72 lb-ft of torque without pushing the truck beyond its comfort zone. The power delivery is smooth and predictable, giving you stronger acceleration when merging or passing while still feeling refined around town. It is calibrated specifically for towing under 8,000 pounds, which makes it ideal for small boats, car trailers, UTVs, or work equipment. Additionally, Smart EGT control actively manages exhaust gas temperatures, so you can focus on the road instead of constantly watching gauges. Low speed trailer maneuvering is improved, making it easier to back into tight spots without the jerky throttle response that frustrates so many owners. You keep your factory exhaust brake and all emissions equipment intact, so reliability and functionality stay front and center.

Intelligent Calibration Strategy Built Around Real World Use

This is not a generic tune that simply adds fuel and hopes for the best. More than 100 calibration changes from stock are carefully implemented to improve throttle response, optimize air fuel ratios, and reduce soot production. The revised pedal sensitivity allows you to shift up and throttle back while towing, making better use of the broad torque curve in the 6.7L Cummins. Furthermore, the included EFI Live AutoCal V3 makes flashing simple through the OBD port, with no wire splicing or sensor modifications required. You can log engine data for diagnostics and apply future updates using the same device, and the required license is included with purchase. For trucks equipped with the 68RFE transmission, optional transmission tuning is recommended to improve line pressure and shift strategy so the added torque is handled properly. The result is a balanced, purpose built calibration that enhances everyday drivability while maintaining the reliability you depend on.
