Tunit provides an efficient and adaptable method of enhancing the power and torque on most modern diesel engined vehicles. It is a retro fit module that will not interfere with original equipment or manufacturers warranty. In most cases it is an easy, quick installation using original style connectors providing upto 30% power increase and 10% increase in fuel economy.



Each Tunit is specifically designed to enhance the performance by modifying the fuel injection parameters and, by careful manipulation of these values, provides optimum performance of your engine. The turbo boost pressure is not directly affected thereby reducing the mechanical stresses imposed on the engine.

There are natural variations in engine performance between vehicles and, for this reason, all Tunits are adjustable either manually or by laptop tuning. Manual adjustment is possible by use of the 9 position dial which can be adjusted by the user. Lap top tuning allows greater control, taking into account any other modifications to the vehicle or indeed to change the power delivery.
