Tackle Tough Tows Without Sacrificing Driveability Or Durability

If your truck hauls heavy and sees hard miles, the DuramaxTuner Heavy Tow ECM and TCM Tuning Package is built to keep it working smarter, not harder. This tuning solution gives your 2013-2014 6.7L Powerstroke chassis cab the low-end torque and clean throttle response it needs to move serious weight without constant downshifting or climbing EGTs. You will feel the difference when you hit the throttle and the truck gets up and moving more confidently, especially with a loaded trailer behind you. Whether you’re pulling equipment, tools, or a service bed stacked with gear, this package helps you stay in control. It’s tuned to work safely with all emissions equipment in place, giving you the performance without compromising compliance or long-term reliability. The added TCM calibration keeps the transmission in sync with the power curve, tightening up shift timing and improving torque converter lockup under load. With RTD hardware, credits, and Bluetooth connectivity all included, this is the one-and-done setup serious work trucks need.

A Fully Integrated Powertrain Calibration Built For Towing Duty

This Heavy Tow package combines custom ECM and TCM tuning designed specifically for 2013-2014 Ford F-250 and F-350 6.7L chassis cab trucks. The ECM tune includes more than 100 individualized calibration changes, delivering a safe +30 rear wheel horsepower and +66 ft-lbs of torque focused on usable pulling power. It retains all emissions components and integrates SMART EGT control to manage heat buildup while towing. Built-in air-fuel ratio controls help reduce soot output and ensure efficient combustion under stress. On the transmission side, the included TCM tuning improves shift strategy, raises line pressure, and adjusts torque converter lockup points to match the new torque curve. This keeps the truck in its powerband longer while reducing short-shifting under load. RTD hardware with Bluetooth support is included, along with the necessary HP Tuners credits to flash both ECM and TCM calibrations. This package is ideal for commercial fleets, over-the-road haulers, and service trucks that tow consistently in demanding conditions.
