the most control is required at low boost settings as the wastegate need to vent more exhaust gas to maintain the lower boost.
Due to the mass flow of your engine Id say either a 44mm gate to a 46mm gate would do fine. We use 44mm gates on our busa engine and have no problem maintaining 6 psi thru redline. This is also with big turbine housings for our engine size.
