Many of today’s turbo diesel vehicles are heavily restricted on performance from the manufacturer. Large gains in power and torque can be achieved through the addition of a Tunit module. The Tunit plugs into the original plugs on the vehicles wiring loom allowing the fuel injection parameters of the engine to be modified. In simple terms more fuel means more power. The Tunit module can be adjusted to give either maximum performance, improved fuel economy or a mixture of both.

The tried and tested units work safely within the parameters of the vehicles ECU so will not damage your engine in any way. Immediately after installation the increase in power, torque and throttle response can be felt giving the vehicle a completely different feel when driven. R-Tec have been approved dealers for Tunit Modules for nearly 5 years now and we are still yet to have an unsatisfied customer. That says it all!
