Optimize your Powerstroke with DuramaxTuner

If you drive a 2015–2016 Ford 6.7L Powerstroke Cab & Chassis and feel like the factory tune leaves something on the table, the DuramaxTuner 4 Tune Pack is built to bring your truck to life. This isn’t about throwing a bunch of aggressive tuning at your engine and calling it a day. It’s a carefully developed ECM and TCM package designed to give you more usable power, better drivability, and real-world reliability, all while keeping your truck ready for hard work. With this tune pack, you’re looking at gains up to 539 horsepower and 1,150 lb-ft of torque—a serious upgrade over the stock 440 hp and 925 lb-ft. What’s great is how natural the power feels. Throttle response is instant, wiping out the sluggish dead pedal feeling that so many stock trucks suffer from. Whether you’re merging onto the highway, crawling through a job site, or trying to back a trailer into a tight spot, your truck reacts when you need it to without hesitation.

Designed for Various Applications

The tuning isn’t just about adding power either. It’s been designed with towing in mind, so it’s safe for use all the way up to your truck’s gross vehicle weight rating. No need to stress about putting heavy loads behind you—the engine and transmission tuning work together to keep things smooth, strong, and under control. Plus, smart EGT (exhaust gas temperature) management keeps your engine running cooler under heavy loads, protecting your investment for the long haul. Fuel efficiency also gets a boost thanks to more refined fuel mapping. That means your truck not only runs stronger but also uses fuel more effectively, whether you’re hauling cross-country or just getting through a busy day of work. And because the tuning burns cleaner, there’s less soot buildup compared to basic box tuners, which helps keep your engine and emissions systems healthier over time. Transmission tuning is a major part of this package too. Shift points are optimized to match the new power curve, so shifts feel natural and help the truck stay in the sweet spot whether you’re pulling hard or just cruising. No harsh, jerky shifts or awkward gear hunting—just smooth, predictable power delivery when and where you need it.

Engineered for Reliability

DuramaxTuner also made sure you don’t lose any factory features you rely on. The turbo brake functionality remains fully intact, giving you that added control when descending grades or slowing down with a heavy load. Plus, everything you need to get set up—hardware, credits, and full support—is included in the package. If you ever need help, their world-class customer service team is just a phone call away. If you want your 6.7L Powerstroke Cab & Chassis to drive the way it should have from the factory—more responsive, more efficient, and more capable—this 4 Tune Pack is a no-brainer upgrade. It’s the perfect way to get the most out of your truck without sacrificing the dependability you count on every day.
