Simulating Quad Turbo Setup?

[Big Poppa Shmee]

So, the odd time I get to play this game I quickly get to work making engines and converting them over to Assetto Corsa, its probably my favorite thing to do with that game. I'd love to simulate a quad turbo V12 but I'm unsure how to do so. As an example, here is a 7.6-liter V12 twin turbo I created to be put in a luxury cruiser. Great torque available down low (can only imagine how much better it would be with twin scroll variable geometry), while powerful but fairly modest top end.

692bhp, 1115nm of torque. Here is how the engine is set. I've already included I believe a 15% drivetrain loss in these numbers.

0|100
500|355.84
1000|386.25
1500|366.34
2000|390.26
2300|497.59
2500|498.64
3000|482.27
3500|468.07
4000|466.82
4500|447.30
5000|424.52
5500|399.61
5700|386.71
6000|366.38
6500|337.53
7000|311.78

Here are the turbo files that the game uses to modify these numbers.

[TURBO_0]
LAG_DN=0.990
LAG_UP=0.9850
MAX_BOOST=0.45
WASTEGATE=0.45
DISPLAY_MAX_BOOST=0.45
REFERENCE_RPM=2300
GAMMA=2
COCKPIT_ADJUSTABLE=0

[TURBO_1]
LAG_DN=0.990
LAG_UP=0.9850
MAX_BOOST=0.45
WASTEGATE=0.45
DISPLAY_MAX_BOOST=0.45
REFERENCE_RPM=2300
GAMMA=2
COCKPIT_ADJUSTABLE=0

Here is the website I use to make a dyno graph. http://jsfiddle.net/x4fab/rw6pug21/embedded/result/

You can pretty easily just copy paste over the relavent information to see the curve. My question is, what would 2 addition turbos do to the curve? Is it simple as just adding 2 turbo's with w/e boost and reference rpm I want (reference rpm is where assetto corsa shows the turbo hitting max boost), and thats it? Or is it a lot more complex than that.

I believe that Bi-Turbo set-ups will be available in a future update but at the moment we are limited to a single turbo (Twin-Turbo on Vee engines).
