Everyday Driving Meets Confident Light Towing

If your truck pulls double duty during the week and on the weekends, this Light Tow Tune is built for exactly that kind of life. It wakes the truck up in a way you can feel right away, without turning it into something temperamental or harsh. Throttle response is smoother, power comes on clean, and the truck feels lighter when you pull away from a stop. When you hook up a small trailer or load the bed with equipment, the tune keeps everything calm and predictable. Low speed maneuvering is easier, especially when backing up or creeping through tight spots. You still keep factory turbo braking, so downhill control feels familiar and confident. It is the kind of tune that makes you enjoy driving your truck again, whether you are commuting or towing on the weekend.

Smart Calibration Built For Real World Loads

This Light Tow Tune is engineered specifically for trucks that tow under 8,000 lbs while still serving as daily drivers. It uses over 100 calibration changes to safely increase power by up to 55 RWHP and 99 ft-lbs of torque without pushing exhaust gas temperatures too high. Built in air fuel ratio limits help reduce soot, while SMART EGT Control actively manages heat when the truck is working harder. Emissions equipment stays fully intact, keeping the tune 49 State Legal and friendly to factory systems. Pedal sensitivity is revised to provide smoother control at low speeds and during trailer hookup. The tune is flashed through the included EFI Live AutoCal v3, which makes updates and diagnostics straightforward. When paired with recommended transmission tuning, overall drivability and gear control improve even further under load.
