Complete 4 Tune Pack for 6.7L Powerstroke

If you're behind the wheel of a 2017–2019 Ford 6.7L Powerstroke Cab & Chassis truck, you already know it's built to work. But if you want it to work smarter and harder, the DuramaxTuner 4 Tune Pack ECM Tuning Kit is the upgrade that takes your Powerstroke to the next level. Designed specifically for chassis cab configurations—from F-350s to F-750s—this tuning package delivers a significant bump in power, smoother drivability, and better overall efficiency without compromising safety or reliability. With this kit, you’re looking at a jump to up to 539 horsepower and 1150 lb-ft of torque from a stock baseline of 440/925. That’s not just more power on paper—it’s the kind of torque you’ll feel every time you roll into the throttle with a loaded trailer behind you. But it’s not just about raw output. One of the most noticeable improvements comes from the complete elimination of the dreaded dead pedal. Throttle response becomes immediate and predictable, making the truck feel more connected and responsive in every gear.

Tunes Tailored for your Truck

Each of the four included tunes is tailored to balance performance and practicality, whether you're towing at gross vehicle weight or simply cruising empty between job sites. The mapping is refined to improve fuel economy while also keeping EGTs in check, thanks to smart, built-in thermal management. You also retain full use of your factory turbo brake, which is a huge plus for those running heavy loads in mountainous terrain. And since this kit includes the hardware and tuning credits you need, it’s ready to install right out of the box with no surprises. If you’re running a chassis cab Powerstroke and want more usable power, cleaner throttle feel, and the reliability to match, this tuning package is built to do the job—just like your truck.
