Sup guys,

on a TT Supra...or ANY TT boosted car, when they say they're running 20 PSI....is that 10 psi PER turbo or 20 PSI per turbo?

20 total.

Both turbos are running at 20 PSI. Each one only provides half the airflow, though. You might have something like 44 lbs/min total at 20 PSI with each turbo supplying 22 lbs/min.
