Calibrated To Tow Without Compromise

This Light Tow Tune includes more than 100 calibration changes from stock to safely enhance performance, throttle control, and drivability. It delivers an additional 55 rear-wheel horsepower and 99 ft-lbs of torque, which helps get your trailer moving without straining the truck. The SMART EGT control actively manages exhaust temps, while built-in air-fuel ratio limits help reduce soot, making it cleaner and more reliable than box programmers. Designed specifically for towing under 8,000 lbs, the tune retains the full functionality of your factory turbo brake and supports smoother low-speed maneuvering. Revised pedal sensitivity and a flattened power curve ensure a more responsive and predictable driving experience in all conditions. This tune is ideal for daily-driven work trucks, service vehicles, or anyone needing reliable towing without the stress of added heat or wear. Combined with EFI Live AutoCal v3 hardware, it also offers data logging, troubleshooting tools, and seamless tune updates for long-term use.
