Premium Tuning Upgrade for 6.7L Powerstroke

If you're hauling heavy loads with a 2017–2019 Ford 6.7L Powerstroke Cab & Chassis truck, you know the stock calibration isn’t always optimized for the kind of real-world towing you do day in and day out. That’s where the DuramaxTuner Heavy Tow ECM Tuning package comes in. This setup is designed specifically for cab & chassis models and focuses on delivering safe, reliable power gains while keeping drivability and factory functionality intact. It’s a smart, targeted upgrade that brings out the best in your truck without pushing it beyond its limits.

Improved Horsepower and Torque

With an additional 30 rear-wheel horsepower and 66 lb-ft of torque, this tune provides the extra grunt you need for loaded climbs, highway passing, and more confident towing overall. Throttle response is noticeably improved, eliminating the dreaded “dead pedal” feeling and giving you better control at low speeds—especially helpful when maneuvering in tight spaces or backing up trailers. The revised fuel mapping not only helps reduce soot compared to box programmers, but it also increases fuel efficiency during long hauls. Best of all, this tuning retains full use of your factory turbo brake and includes smart EGT management to keep your exhaust temps in check automatically. The package comes complete with the required hardware and credits, plus it’s backed by real, knowledgeable phone support if you ever need help dialing things in.
