dyno simulators and turbos

i have been given a copy of dynosim to have a play with and am curious how you proceed to allow for a twin turboset up i can get the specs for a single turbo which is island flow, surge flow, pressure ratio, and peak efficiency and boost - now for twin turbos do i just double one of these cos that seems to lose power any help?

In theory you should just double the flow rate if you are using 2 of the same turbos in Parrallel.

Why don't we move this over to the turbo forum where the experts hang...

That seems rather odd.
So you maintain the same boost pressure etc. and just double the flow rate and you loose power... hmm...
I have never used dynoism, so I am not really sure. The only virtual dyno program I have used is Virtual 4-Stroke...
Anyone else used the program, or have any ideas?
