    Default power question

    hi guys, as some of you know ive just got my vectra.
    i must say im very happy with it but i feel it should be faster..

    when i floor it, theres no smoke at all that i can see anyway,
    theres no error codes or anything..
    boost kicks in at 2k rpm and dies about 3..? roughly.

    wats e best way to get better power where the turbo stays spooled for more revs etc..?

    any one in glasgow fancy lending a hand to clean the egr valve and the boost sensor?

    Martyn

    An 05 SRi CDTi 150
    What sort of mileage is it on?
    Whats the service history like?

    There should be little power up to 2K revs then it should pull like a jet!
    Loss of revs at and above 3K is wrong, it should keep increasing, getting to about 4.5 then flattening out

    its got 101k full, service history (was a company car) engine is immaculate.
    it dosent state if glow plugs or anything has ever been changed.
    it dosent just stop as such, its like after 2k theres power but its like a surge n sorta drops off..

    Turbo should kick in before 2k too.... 2k is too late and signifies something needs cleaning (EGR, Boost Sensor, swirls... ).
