I get quite a few people come to me with issues like this and its just the spring causing is from the constant adjust and re adjust. You'll get it soon enough mate.
    Guys should I be able to hear the ball bearing rattling around when I shake the dawes valve with the engine at idle? I am a bit confused over the fact that the actuator arm doesn't move when I turn the needle valve either. Could this be a source of issue?

    No mate. You have the dawes open way too much if the ball is rattling. Screw in the dawes and try the needle valve adjustment then. If no joy, the diagram in the actuator could be stuffed. The other side of the needle valve. Where is it plumbed in to?

    That sounds like it could be the issue.
    So winding the dawes in will reduce boost?

    Winding in will increase boost. Take the boost hose off the dawes as it sits now. Before you touch it again. And see if you can blow air though it with your mouth.

    So wind it in until I can not?
    If you can, the boost won't rise, any boost pressure will just pass through the ball in the dawes. Wind it in atleast half way and then wind the needle valve in also, right in. (To shut the vacuum supply right off) Then start the car up, and unwind(open the vacuum supply) the needle valve until the rod drops. If it doesn't drop, I would think it's either incorrect plumbing or the actuator is stuffed. Think.

    Cheers mate
    I will go and give it a crack.
    I have double checked the plumbing a few times against the instructions you emailed the other day.
    thanks again for that

    dawes set up 1.jpg
    So this is the set up I think it shows all the parts in the set up.
    I can only get 5 psi out of it at the moment.
    I put a new spring in today (thanks for the fast shipping Mudski)
    I will keep fighting the gremlin just posting an update.

    O.k First thing I notice is the dawes is almost upside down, sort of, lol. I may not affect anything but its best to have the dawes sitting vertically. It just eliminates the possibility of the ball not seating itself right. Next is the clear plastic hose and the Y piece you have, those plastic pieces are prone to crack and leak. The plastic hose I take it goes to a boost sensor or something?
    Can you take a pic of the other side of the intake hose? The needle valve is hiding the plumbing behind there.
