4 Tune Pack with Hardware

If you're running a 2011–2012 6.7L Powerstroke Cab & Chassis and want to unlock its full potential without compromising drivability or towing capability, the DuramaxTuner DT1300230102000 4 Tune Pack is exactly what you’re after. This isn't some off-the-shelf flash tuner—this is a carefully engineered ECM and TCM tuning package that delivers real-world gains you can feel, backed by proven reliability and world-class support. Right out of the gate, this tuning package can bump your output to 539 horsepower and 1,150 lb-ft of torque—up from the stock baseline of 440 hp and 925 lb-ft. That’s a huge jump in performance, and it's not just about making more power for the sake of numbers. What really sets this tune pack apart is how smooth and usable that power feels across the RPM range. Acceleration is quicker and more responsive, with the dreaded dead pedal issue completely eliminated. Throttle response is crisp and immediate, making the truck feel far more connected to your foot—especially helpful when maneuvering at low speeds or pulling out into traffic with a heavy load.

Improved Performance Across the Board

Towing performance is another area where this package shines. These tunes are engineered with safe towing in mind, right up to your truck’s gross vehicle weight rating. You’re not sacrificing reliability to gain performance here. In fact, with smarter EGT control and improved fuel mapping, you’re likely to see lower exhaust temps under load and better fuel efficiency across the board. Whether you’re pulling equipment to the jobsite or hauling freight across state lines, the truck will run cooler, cleaner, and more confidently than it ever did stock. Transmission tuning is included as well, which makes a bigger difference than most people expect. Shift points are refined to match the added power, so you're not stuck with clunky gear changes or early upshifts that bog the engine. Instead, shifts are smooth, timely, and optimized for both performance and longevity.

User-Friendly Design

You’ll also appreciate that all factory functions are retained, including the turbo brake. This means you’re not giving up control or safety features to get more power. It’s everything you want from a custom tuning package—clean, reliable performance that fits the way you actually use your truck. Best of all, this kit includes the required tuning hardware and credits, so you’re not left chasing down extra pieces or hidden costs. And if you ever hit a snag or have questions along the way, DuramaxTuner’s world-class phone support has your back.
