No more needing to remove and swap your existing ECM. Within 30 minutes you will 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 light or heavy towing, fun daily driving, or ultimate engine performance. Get the cleanest and most reliable tuning available for your L5P Duramax.

Unlike box tuners, our tuning can be designed to take into account other modifications like upgraded turbos, aftermarket intakes, and built transmissions. This can help improve the performance gains seen from these modifications. Your tunes will also be optimized to work with your 6 or 10-speed transmission. Precise fuel and timing adjustments mean less unburnt fuel than box tuners. This results in less soot out the tailpipe, less DPF accumulation, longer intervals between regens, and less wasted fuel.

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.
