Perhaps the wrong question, as the amount of boost is variable, whatever, within limits, to achieve target air mass flows. Not a simple pressure.
And for a given air mass flow, the torque depends on temperature and intake restrictions, as these affect how much the wastegate is closed to generate the turbine shaft power required to get the air mass flows.
So for a given ECU, fitting a better IC and downpipe etc, would yield more torque and power than the stock items, even for the same air mass flow.
I have not seen anything other than published vendor curves.
