Heavy Tow Tune Only for EFI Live Spade - Cummins CMD (2010-2012)

This Heavy Tow Tune is designed for 2010-2012 RAM 2500/3500 6.7L Cummins trucks that regularly tow up to gross vehicle weight. It provides a modest increase of 20 rear wheel horsepower and 36 lb-ft of torque to assist with heavy loads. The tune features Smart EGT control to manage exhaust gas temperatures, and revised throttle sensitivity for smoother low-speed trailer maneuvering. It maintains factory emissions equipment and exhaust brake functionality. Over 100 calibration changes are implemented for high load conditions, including air-fuel ratio limits to reduce soot. The tune requires EFI Live AutoCal V3 hardware for flashing through the OBD port.
