4 Tune Pack for Cab & Chassis Ford Powerstroke

If you're running a 2011–2012 Ford 6.7L Powerstroke Cab & Chassis and want to get more out of your truck without sacrificing reliability, the DuramaxTuner 4 Tune Pack delivers a well-rounded performance upgrade tailored specifically for your workhorse. This isn’t just about throwing more fuel at the motor, it’s a carefully developed tuning package that enhances how the truck responds, pulls, and drives in real-world situations. With this tune pack, you can see output climb to 530 horsepower and 1123 ft-lbs of torque, up from the factory baseline of 440/925. But the numbers only tell part of the story. One of the biggest improvements you’ll feel right away is the elimination of the dead pedal. Throttle response becomes immediate and predictable, making the truck feel much more responsive, especially at low speeds or when trying to navigate tight spaces.

Optimized for your Ride

Each tune is optimized for different needs, whether you're towing, daily driving, or simply looking for smoother power delivery. These calibrations are designed to be safe for towing at gross vehicle weight, so you’re not trading performance for peace of mind. Improved pedal sensitivity makes the truck easier to manage at low speeds, and smart EGT control helps keep exhaust temperatures in check automatically, so you’re not constantly watching a gauge while working the truck hard. Fuel mapping has been reworked for better efficiency, meaning you get more power with less wasted fuel, and less soot. Plus, you’ll retain full factory turbo brake functionality, which is a major plus when you're hauling heavy loads and relying on engine braking to help slow things down. Backed by DuramaxTuner’s trusted customer support, this 4 Tune Pack gives your Powerstroke the power and drivability it deserves, without compromising on durability. It’s a practical, performance-minded upgrade for anyone who depends on their truck day in and day out.
