So update: On my N55, which still has full extended warranty, BMW replaced the pressure converter as mentioned by Feuer, off the waste gate valve. They tested turbo and its responds to test, fully moving waste gate.
I suspect these parts as an old mechanic once said it, they get "lazy" after a while. They may still work, and not throwing code all the time, but not fully functioning all the time. BMW said they didn't really know if it was that part or not, but seen it before, so they threw a new one on.
Response is really good now. Ready for Track day in June, 1st time. Hope it goes well.
Looking to do Dinan Stage 2 tune next, but likely wait until my warranty comes fully due.
