Being competitive in diesel motorsports means constantly trying new turbo and injector designs. These new designs have the potential to dramatically shift the operating range of the engine, and in some cases push cylinder pressure to the bleeding edge. We at Duramaxtuner have the tools and experience to dial in your custom built Duramax. Let us custom build the fuel and timing curves for your custom setup. Avoid smoking, rattling, and lagging associated with other programs. Get in contact with us before or after your build to arrange time to dial in your setup. Tuning can be done in person or remotely with real time support.

*Five postiion tuning avialable for '01-'05 trucks.
**Customers in the midwest are encouraged to schedule live tuning.
