No more struggling to maintain your speed on the highway or sluggish acceleration when towing. In just 30 minutes you'll be able to unlock and flash tuning onto your truck's existing ECM. You will have total flexibility to switch between custom tune files on the fly, giving you the power for heavy towing, fun daily driving, or ultimate engine performance.
We know the number one issue these trucks face is lack of power, especially when it comes to towing. Our tuning provides a significantly wider torque curve compared to stock. Allowing you access to more power across the entire RPM range. The additional low-end torque makes getting loads moving a breeze. Plus it allows the engine to shift up and throttle back when driving on the highway. This can even result in fuel savings. With all of that additional power, there's no more struggling to maintain your speed while towing either. Just sit back and enjoy being able to use your cruise control again.
With over 100 engine parameter adjustments compared to stock, Custom Tuning provides the most complete and powerful engine tuning possible. In Addition, your engine and drive train safety is our top priority. We keep factory EGT limiters and other safety features in place to ensure your engine stays protected. Along with that, we have over 15 years of Duramax tuning experience. We know what these trucks are capable of and how much power they can safely handle.
