4 Custom Tunes for your 6.7L Powerstroke Cab & Chassis

If you're running a 2017–2019 Ford 6.7L Powerstroke Cab & Chassis truck and want real flexibility without compromising safety or reliability, the DuramaxTuner 4 Tune Pack gives you exactly that. Whether you're towing, daily driving, or just want to feel more connected to the pedal, this pack delivers clean, tailored performance across multiple driving scenarios. Each of the four included tunes is designed with a purpose—from heavy tow all the way to max effort. You can expect up to 539 horsepower and 1,150 ft-lbs of torque at the top end, compared to the factory baseline of 440 HP and 925 ft-lbs. But it's not just about peak numbers. These tunes are refined, well-balanced, and calibrated to keep your engine running cool and your transmission happy—even under heavy loads. Throttle response gets a major upgrade with complete dead pedal elimination. You’ll feel the difference as soon as you touch the throttle—especially helpful when you’re towing, navigating tight job sites, or just cruising around town. Low-speed maneuvering also improves thanks to revised pedal sensitivity, giving you smooth, predictable input without any lurching or lag.

Smart Tuning Technology

The tunes are smart, too. EGT control is baked in, keeping exhaust temperatures in check during demanding conditions like towing uphill in the summer heat. And unlike some tuners that disable important factory functions, this pack retains full use of your turbo brake—so you don’t lose any stopping power when you need it most. DuramaxTuner also designed these calibrations to be more efficient than generic box programmers, meaning less soot output, cleaner engine operation, and potentially better fuel mileage depending on how you drive. And if you ever have questions or need help switching tunes, their customer service team is known for being some of the best in the business.
