Rounded and assuming 1000mbar atmospheric pressure.

Cc of engine - 2000
Cylinders - 4
Maximum cc of air per cylinder at atmospheric pressure and 100%VE - 500cc

500cc per stroke at atmospheric pressure and inlet temperature of 35*c = 575mg

1bar boost pressure = 1150mg/str
1.5bar boost pressure = 1437.5mg/str

Now assuming this is what you guys are referring too (please confirm) I would like to discuss further, want to check we are on the same page first though.

EDIT -
Taking this a step further and adding estimated intake temps (not logged) and estimated VE. Some figures are false, but it will prove the theory if correct

And with the fault condition present -
