I got an External Wastegate by SSAutoChrome, but I'm using an Electronic Boost Controller... here's the pic:

I don't know a whole lot about the wastegate, but i am gunna guess that it may be the problem. Their quality isn't known to be the best. Your best bet is to buy a tial. Even if the problem persists atleast you got a better wastegate.

yesterday I removed the wastegate, and closed its flange, nothing leaked out, and same....

have you boost leak tested the whole system?

Do you know what spring is in the gate? If you blocked off the wastegate hole and get the same reading you do when the wastegate is on then the wastegate is not opening at all. I hope I am reading your post correctly, it is kinda confusing. I would double check to see what spring you have.
