what the noise was, was the wastegate chattering.
basicly i had a blue spring. hadnt even touched it from my last set up last year so i didnt even think of it silly enough.
so the dv wasnt opening when boost built up to control it. it was then over boosting, throttle body would close so the gauge wouldnt read it (tapped into mani). it would then cause higher pressure on the under side of my wastegate and less on the top due to the bleed valve and wastegate would open....then get to a desired boost so close, open, close etc......causing the noise and
problem.
why a mapper couldnt see that i dont know. and why they thought it was surge is beyond me.
so im gonna need the map tweeked again but it is massively faster
