Smart Tuning That Delivers Reliable Real World Gains

This Light Tow Tune includes more than 100 calibration changes to optimize power delivery, transmission behavior, and engine safety while towing up to 8,000 pounds. Designed specifically for the 2015-2016 6.7L Powerstroke Chassis Cab, the calibration incorporates SMART EGT Control to automatically manage exhaust temperatures in real-time, protecting your engine even under load. Air-to-fuel ratio limits help reduce soot output, keeping emissions systems cleaner over time and improving long-term reliability.
