Premium Tune Pack for 6.7L Powerstroke Trucks

If you’re running a 2015–2016 Ford 6.7L Powerstroke Cab & Chassis setup and want to unlock more usable power, cleaner performance, and tighter throttle response without sacrificing drivability or towing safety, the DuramaxTuner 4 Tune Pack is the upgrade you’ve been looking for. This isn’t just about chasing dyno numbers—it’s about improving how your truck performs and feels every single day, whether you're loaded up for work or just cruising light. This 4-tune package gives you access to a carefully engineered lineup of calibrations tailored specifically for Cab & Chassis configurations. Each tune is built with safety, longevity, and versatility in mind—ranging from daily driving and light towing to full-power, high-output performance. Expect gains up to 539 horsepower and a massive 1150 lb-ft of torque, a serious bump from the factory baseline. But it’s not just the numbers you’ll feel—it’s the sharper throttle, the elimination of that frustrating dead pedal lag, and the way your truck pulls stronger and smoother across the entire RPM range.

Stay in Control on Every Adventure

Behind the wheel, you’ll notice a more refined driving experience with improved low-speed control—ideal for maneuvering around the job site or backing a trailer. Smart exhaust gas temperature (EGT) control ensures your powertrain stays protected, especially under load or extended climbs. And since these tunes retain full factory turbo brake functionality, downhill control remains just as dependable as stock. Installation is straightforward and supported by DuramaxTuner’s renowned customer service team. You’re not left guessing—just solid performance, plug-and-play usability, and dependable results. If you're building out a reliable workhorse that also knows how to have a little fun, this 4 Tune Pack is a smart, balanced solution that delivers where it counts.
