It uses innovative digital microprocessor technology to allow 9 pre set tuning maps to be loaded onto the box. Each map has slightly varying parameters enabling us to select the best one that suits your engine and driving style characteristics. The tuning maps created are designed to deliver a smooth and efficient increase in performance which improves the driveability of your vehicle dramatically.

Therefore you get the best power, torque AND fuel economy when you have the most efficient tuning map. It is the quality of the programmed tuning maps which really sets the Speedhawk diesel tuning box apart from the rest.
