REVIEWS

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.

Many thanks for the customer support enquiry. The answer is Yes we managed to fit the device successfully. We have left it on the factory setting 5 and it has transformed the engine. It has improved the fuel burn from cold , the engine smoked a little originally even though it had only covered 20,000 miles. It is noticeably more powerful through the rev range and clearly has more torque than the stock programming. We are very pleased so far and would recommend your product. Kind regards Stewart
