Ok guys, here is the update. I need some technical advice about what happened.

I had a joeP MBC installed by a shop. I ran my car like normal for a few stop and go runs..about 60 miles. The BOV had stopped making that whistle pop at throttle release the second the MBC had been installed. Instead it made a huge flapping noise. And my car seemed slower than before

The MBC had been installed WRONG. At home, this is what I saw: the MBC had one tube going into the BOV, and one tube going into the surge/boost tank (right after the T-connector for the boost gauge). I removed the MBC and replaced the BOV to surge tank conenction with the stock 3/16" ID (inside diameter) hose. Again, a test run still yielded a huge pfffssshhttt sound at after 5psi indicating a major loss of power (boost leak was obvious). Nothing had changed.

After 1 hour, I took it for a test run, and everything was PERFECT. The BOV made its wihtling and sharp psstt noise at soft setting and the car ran fast. No power loss. Everything good.

Questions:
1. what effect did the wrong tubing of the MBC have on the car in terms of airflow and boost?

2. why did my replacing the MBC with stock tubing not solve the problem immediatly, and took 1 hour?

Thanks. Just trying to get to know more about how things work (or don't work, hahaha).
