Log your waste gate duty cycles and see if they are maxing out to near 100%.

There are a lot of fake HKS Bov's.

Whether that is your problem is irrelevant though, it needs ot be solid on the pipe or it is likely leaking. The HKS flange on the ER charge pipe is good, so it may be a bad seal/ o ring or retaining clip, as mike said.
