    Is the fuel filter choked .or have you changed the tank cap ,and there is a vacuum in the tank .....Sounds like fuel starvation...

    So are you saying that as soon as you hit an incline at cruising speed, you have to depress the throttle so far that it kicks down and the revs go very high?
    If so, it might be a gearbox issue?

    ok guys thanks I take the point. sorry. I have been beating my head on this thing since May and Im getting a bit punch drunk. The guy has fiddled with so many things on it Im not trusting anything I see. I even found missing engine mount nuts under the turbo so..I have no idea what Im working on at the minute. Ill keep my questions to my posts from now on. ;)

    Probably best but I would not worry too much as hijacking and chaos reign supreme here. It is hard enough keeping people on topic.

    It does the same if I want to overtake and give it some welly it hits 50 mph and won't change gear unless I lift off for a few seconds then back on again but it doesn't always happen it's ran for a few weeks now no problem after I changed ecu sensor like wammers suggested and all of a sudden it's playing up but it's like sometimes it does sometimes it doesn't it's had new ecu sensor fuel filter and changed boost pipe last night made no difference

    Link doesn't work

    Sorry, no, it was my phone.

    That looks more like a gearbox problem than engine issue

    Try putting it in 3 and see if it does the same.
    Would be good to get some diagnostic on it really.

    It makes no difference if I try to change gear when it's doing it I had it on the nano com and no faults show

    Did you check the gearbox for faults?

    Shouldn't be around the 4000rpm mark at 50!! I would agree with wazzajnr.
    Have look at your gearbox oil level recently? Any leaks around the g/box sump or cooler under your bumper?

    New sensor fixed it and now intermittent? What about the wires to the sensor?
