I have fitted the unit onto the X-Trail, it took about 5 minutes, it is now like a different car! I?m currently experimenting with the different settings but the car runs great on the standard setting. What I?m most impressed with is the change to the smoothness when accelerating, instead of the jerky delayed response the car now responds as soon as your foot touches the pedal. The torque increase is great and the power, in terms of smooth accelerating is amazing; I know it?s a 4x4 but it feels like a car when driven. The investment is well worth it given the scale of change to the performance; I?m sure once I stop taking advantage of the keen acceleration that I?ll start saving money on fuel but at the moment I can?t resist the temptation to floor it!
