I own a mkII xr6 turbo, and from the moment we bought it I believe the fuel gauge and trip computer are reading incorrectly. it seems to be out by 10-15ltrs, I have been told a couple of different things from ford, but don't seem to be getting anywhere. I have also notice the best I can get out of the trip dte is about 480km whether I drive on the highway or around town. other this it has been great, am also looking at maybe putting in a k&n filter, has this helped anyone?
