Are you sure you're not cranking it closed? 0.05 is around wastegate pressure. A quick test would be to unplug the hose leading out of the boost T...go BRIEFLY full throttle (dangerous if you sustain this AT ALL). If you make more boost...your MBC is messed up.
Another thing to check is that the plastic restrictor in the line is not melted shut.
Good luck, and ditch the MBC for something better.
