Heavy Tow Tune incl EFI Live Spade - Cummins 6.7L (2013-2017)

This Heavy Tow Tune from DuramaxTuner, including EFI Live Spade AutoCal V3, is designed for 2013-2017 RAM 2500 and 3500 trucks with the 6.7L Cummins engine. It's built for safely towing heavy loads and maintains all factory emissions equipment. The tune features over 100 calibration changes from stock to improve towing performance, actively manages exhaust gas temperatures, and reduces soot production under load with built-in air-to-fuel ratio limits and SMART EGT control. It's engineered to support trailers up to 8,000 lbs GVW while retaining full factory turbo brake functionality and drivability. The tune also improves pedal response for predictable acceleration and smooth low-speed maneuvers when towing.
