I was driving along a dual carrigeway, put my foot down and no power, no dump valve, got home and one of the hoses had came off, put that back on, just been out in it again, and i have no boost, the dump valve is working but quiet, i looked at the gauge and it stays in the green

I haven't fooked my turbo have i?

 

Are you getting any boost? If not then its sounds like the actuator may have come off its pin/post on the wastgate.
