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.
Very, very impressed. Totally transforms the vehicle. Pulls from much lower down, smoothing out the point where the turbo comes in. An absolute joy to drive. I'm sure you've had all the superlatives before from previous customers but I honestly think it one the best things I've ever bought and for this reason I'm recommending to anyone I know who wouldn't be bored with me banging on about engines.
