Tuning

What is Tuning?

By choosing a custom tune, you can refine engine and transmission parameters beyond standard factory settings. Many owners seek custom tuning to maximize thermal efficiency and optimize combustion timing. By refining the combustion cycle and streamlining internal engine processes, we can extract more energy from the fuel than previously possible. This calibrated tuning ensures the engine operates at its peak mechanical potential, often resulting in improved throttle response and enhanced overall efficiency.

Single Tune

A single tune option is perfect for customers who are just looking for a mild tow or economy tune and do not foresee the need to switch tunes. The truck will always run it much like the stock tune, perfect for customers who are not the only ones driving their trucks. We can set up a single tune to any power level or configuration.
