Increased Fuel Efficiency, Power and working MPH!

Tractors and other agricultural vehicles require sufficient power to handle heavy work loads.
Too much load on an engine can lead to poor fuel consumption and also premature engine wear,
especially to the engines bottom end bearings!
HDT's tuning and plug in units SAFELY increase the engines power output allowing
the engine to do the same work it struggled with before with less load and increased speed
allowing a significant reduction in fuel consumption.

This user friendly touch screen flash tuner allows you to read the information from the engine computer using the diagnostic connector located in the cab and takes only minutes to complete. Once the stock engine tune file has been read you can now unplug the tool and continue operating the machine as normal.
