Hi guys, don't have EB but from your graphs were is the boost in your graphs being read from ?
I ask cause were you should see most delta with a BV is from the intercooler output(before TB) to IM (after TB).
If the BV was faulty, not working you should gets spikes when you let off throttle in the hot side pipe but the IM shouldn't be affective to much as I "think" throttle closes as one of safety features (anyone correct me as again never tuned one).
Anyway, if say you wen 3rd gear pull with relative slow throttle to WOT and let throttle off very slow, if boost is still very high (during the pull mid way) then IMO its not BV, but WG, at least on stock car.
Of course replacing the BV is simple mater to test it out.
Are you using the extra spring ( I saw one BV+ and there was optional spring) maybe try removing it if you do see spikes going away or better talk to manufacture, maybe he is not aware of this issue.
