Confidence When The Trailer Is Heavy And The Road Gets Steep

When your truck spends most of its life under load, power alone is not enough. The DuramaxTuner Heavy Tow Tune for 2015-2016 Powerstroke chassis cab trucks is built to give you steady, controlled performance when the trailer is hooked up and the miles keep coming. Instead of chasing big peak numbers, this tune focuses on usable torque that helps get heavy loads moving without drama. You will notice smoother acceleration from a stop and the ability to stay in the gear you want while climbing grades. Exhaust temperatures stay in check, which matters when you are towing through hills or long stretches of highway. The factory turbo brake still works exactly as it should, giving you better control on descents. If your truck works for a living and reliability matters as much as capability, this tune is designed to support both.

Heavy Tow Calibration Engineered For Thermal Control And Longevity

This Heavy Tow Tune is a custom ECM calibration developed specifically for 2015-2016 Ford F-250 and F-350 6.7L Powerstroke chassis cab applications. It keeps all emissions equipment intact while applying more than 100 targeted calibration changes from stock. Power gains of roughly +30 rear wheel horsepower and +66 ft-lbs of torque are delivered in a controlled manner to support sustained towing. Custom SMART EGT control actively manages exhaust temperatures, while built-in air fuel ratio limits help reduce soot production under load. The tuning strategy is designed around towing loads up to 8,000 pounds GVW, where stability and heat management are critical. Flashing is completed using HP Tuners RTD hardware with Bluetooth support and access to VCM Scanner diagnostics. For best overall drivability and gear control, matching TCM tuning is strongly recommended, especially on trucks with heavier service bodies or frequent towing duty.
