Is this able for 30ff code to come on and have like 150 ho if that?

Yes that’s it, you don’t have a boost leak though. Your wastegates cannot operate with no vacuum. You have a massive vacuum leak now so you’re not making any boost.

Easy fix, buy some vacuum line and a hose splice and reconnected everything, and the wg will operate like it should.

It's actually pretty easy to replace that whole piece, follow it down and you'll see all you have to do is pinch it both sides and pull it out
