You think they're going to risk telling owners what the engine can take with FI solely on lab tests? Don't be silly.
That said, it would be extremely complicated to model all the forces put onto every component in the engine under real conditions in a laboratory test. There are so many different thermal and mechanical loading conditions happening so quickly in the engine that predicting and isolating the worst case scenario for each and every component and then coming up with a test setup to replicate those conditions would be extremely difficult.
Definitely not worth it to Toyota or Subaru since as has been stated over and over again, there will be no factory forced induction. And it's very easy for them to put the TRD supercharger on a few test cars to determine whether it's going to impact long term reliability at 5 psi or whatever low number they'll use. Much, much easier than lab tests.
(I'm not just being a downer here, I worked as a structural test engineer for a while. Things get uber complicated when you're talking about an assembly as complicated as an IC engine with as much going on thermally as an IC engine on top of the mechanical stress)
