Performance Boost you can Feel

Behind the wheel, you’ll notice immediate improvements. The dead pedal feeling that plagues many factory trucks? Gone. Acceleration is crisp, pedal response is sharper, and low-speed maneuvering becomes smooth and precise thanks to revised throttle mapping. The tunes also make better use of fuel, giving you improved efficiency without compromising power. DuramaxTuner didn’t stop at just performance either. Built-in Smart EGT control keeps exhaust gas temperatures in check, so you can push your truck without worrying about overheating. Best of all, there’s no need to reflash or fumble with external devices each time you want to change tunes—it’s seamless and user-friendly.
