Not sure i understand your question but:

when your boost map demands ex. 2200mbar (absolute) then you have 1.2bar pressure at sea level. if your engine is a 2.0liters 4 cylinder, then you have 500ccm pr cylinder. so 500 * 2.200 = 1100 g airflow entering each cylinder at a boost pressure of 1.2bar.

There are for sure other Things as flow efficency/ VE of the engine, EGR flow, that depends on this. but just do some logging then you will see.
