DYNO Tuning

Modern engine management tuning is half science, and half art. We take our time with each calibration, to ensure maximum performance and safety across the entire RPM range. Unlike other dynojets found, we are the only facility to offer the Eddy Current Load Absorption Unit, Torque Cell, and dynamic load control software. With this unit we can perform loaded tests, including step, sweep, and wind drag simulation. What does that mean for you the customer? Better fuel economy, more midrange power, and no hesitation issues since we can hold your engine at a steady load and calibrate any parameter/cell as needed. We offer tuning for a wide array of both piggy back and stand alone engine management services.
