Heavy Tow Tune for 6.7L Powerstroke

If you’re hauling serious weight with your 2017–2019 Ford 6.7L Powerstroke Cab & Chassis truck, you need a tune that’s built to handle the load—reliably and safely. The DuramaxTuner Heavy Tow Tune was developed specifically for trucks working near or at their gross vehicle weight rating, giving you clean, usable power without sacrificing drivability or durability. Right off the bat, this tune delivers an additional 30 rear-wheel horsepower and 66 ft-lbs of torque. It’s not about flashy numbers—it’s about real-world gains where you actually need them. That extra power smooths out hill climbs, improves throttle response, and gives you the confidence to merge, pass, and maintain speed under load, even with a heavy trailer behind you. Throttle feel is also significantly improved. The revised pedal sensitivity and dead pedal elimination make a big difference, especially when maneuvering at low speeds or backing into tight spots with a loaded trailer. It feels more responsive without being jerky or unpredictable, which makes long hauls a lot less tiring.

Major Boost in Engine Performance

Behind the scenes, smart tuning strategies are working to keep everything running cool and clean. The tune actively manages your exhaust gas temperatures (EGTs), ensuring they stay within safe limits even on extended pulls or in hot weather. Fuel mapping is more efficient, which means better economy and less soot—so you're not constantly cleaning up after a dirty tune. Best of all, the factory turbo brake stays fully functional, which is a huge asset when descending steep grades or controlling speed with a heavy load. And if you ever have questions or need help dialing things in, DuramaxTuner’s customer support team is just a phone call away.
