Twin turbos/desktop dyno...

I've been trying to simulate twin turbos on desktop dyno 2000, but the program only allows for one turbo. What I've been doing is double the flow and pressure ratio ratings for a particular turbo and it seems to work, but is it correct?

Pressure ratio @ sea level is calculated by (Boost Pressure + Atmospheric Pressure)/ Atmospheric Pressure

Boost + 14.7
------------- = Pressure Ratio
14.7

Lets say that you are well above sea level and only have 13 psi of atmosphere.

Boost + 13
---------- = Pressure Ratio
13
