Each work assignment is more profitable and productive - Turn your tractor into a powerhouse for a higher work performance and improved fuel consumption. With an additional increase in performance, your tractor is an essential component for the profitability of your business.

Injector Control - Unlike most other products on market, HDT connects directly to the injector using the factory signal from the ecm. Once the signal has been captured by the HDT performance module it modifies the Injected quantity values and Timing Values. While other manufacturers try to "fool" the system into injecting additional fuel by raising fuel pressure or tricking the air temp sensor into thinking it is extremely cold outside we work directly with the injector - which is the safest and correct way to tune an engine!

Safe & Reliable - This unit has the important task of continually monitoring the ECU’s signals to the engine and safeguarding them against any overloads. The protective functions of the ECU remain intact and within specification, ensuring complete peace of mind.


Multi-Map Technology -  4 maps are stored in the chip tuning box, which are activated when needed. This means optimum power and torque, combined with a very low fuel consumption.
