    Puzzled by poor running

    Im really stuck now any help would be appreciated.
    I posted yesterday saying there was no boost I checked pipes and connectors
    all ok. I then checked dump valve and found it only opens at high revs and then doesnt close when lifting also the boost pipe starts to suck inwards indicating that there is pressure in the system. I have put the car back to std now without DV and it is still the same the car drives normally minus any boost. The rev counter goes around and the car doesnt pull at all.
    any ideas welcomed thanks
