Wastegate issues...i think

Where? This isn't accurate... at least not for the situation I think you're describing.

Ok, flutter = b a d. I'd need more specifics to really give any opinion on the "woot" you're hearing. The discharge sound will vary depending upon the configuration of the vehicle's intake. The Bosch sounds much like the stock BPV but as you didn't have a good one to start with it's a moot point. If you have a large, open element air filter you'll have a louder "woosh" kind of sound. Check your vacuum tubing to be sure there aren't leaks which may be causing the BPV to open slow or just partially.

There should be no sound WHILE you are boosting. If there is the most common causes (as well as causes of the code 34) are: #1 boost leak, #2 bad AFM, #3 shot wastegate and #4 bad turbo.

An improperly setup EBC shouldn't really affect the vehicle as you are describing but anything's possible. A wiring problem would be more likely. Personally, I'd remove the unit until everything else is fixed.
