    Sounds like your hitting limp mode probably due to overboosting. The ECU prevents engine damage by restricting the RPM. Possibly a DV fault. Can you get it scanned?

    Thats a bit of a sweeping statement!!! has the car been checked for fault codes? if so do you know what they are?

    Sounds like limp mode but without checking the codes in the first instance then its gonna be difficult to start suggesting much more than checking all hoses and pipes for signs of leaks/splits etc.... the PCV pipes under the inlet manifold are classic areas for leaks and a big boost leak will throw a boost deviation code and go into limp mode... does the CEL (check engine light) come up on the dash when this happens?
