I wouldn't mind upgrading my wastegate anyway as i want to change it to Vband because the adapter plates have slight little leaks as it's been removed a few times, and it'll eliminate gaskets (which caused a boost creep as the bolt came out and gasket moved down and blocked the wastegates flow path)
It's something i can think about doing

Said differently, have you tried values for GP lower than 11 psi, and does it make a difference?

i will have to lower it to at least 10 psi, i'll do this friday as i now drive the car on weekends mostly.
I understand his post. it makes sense, that's how i did mine, but it was in 3rd gear.
I'll do it and report back. Thanks for your help

I've gotten down to 9psi got the gate pressure. and it still overboosts.
I am going back to dualport as i never went this low before and test it on that.

So i changed back to dual port. put the start boost (gate pressure) at 0 and it boosts like it would boost with a MBC.. im guessing because it's already regulating boost when it sees 0.1 psi and no overboost so far and it was raining which means moist cold air (where it over boosts the most).
So far so good.
So far so good.
