N54 not making over 1.4psi

I need help. Never posted bfo but I js need advice. I was running the MHD OTS stage 1 map and then suddenly lost all boost. It whines on when trying to hit boost. I smoke tested and found a giant leak from charge pipe connection to throttle body so bought new O ring smoke tested again got really excited put everything back together and same issue. I can post data logs if that can help narrow it down but I’m throwing no codes at all. Flashed back to stock just incase it has smth to do with the tune but still same issue. I don’t have money for turbos rn so I’m really hoping it’s not that but I don’t know what else it could be. I’ll post a video of the noise it’s making on acceleration At this point I’m just stumped. Waste gates seem to be opening and closing just fine. I watched them while having a buddy hit the gas. Any help would be nice.
