REVIEWS

Rob ,Landrover Discovery TDI 2.5 Au

The landrover has inceased in both torque and power, but mostly noticeable in pulling the horse box up hills, rather than increased speed. But it is faster pulling away from junctions.

Nigel,Nissan X-Trail 2.2 DCi

I bought a Tunit unit for my Nissan X-Trail with some scepticism. I fitted it very easily and then the surprise, it transformed the car.

Much better acceleration, more flexibility and just much more enjoyable to drive, and all this from the standard setting. I am using no more fuel for this increase in performance, and use less than I was in normal day to day driving.

Go and buy a tunit, you will not be disappointed.
