They're designed for the stock turbo which is much different than the PS2.
Say you were running stage 2+ FBO on a stock turbo and then just upgraded to a PS2, wouldn't it just be easier for the PS2 to make the same boost without closing the wastegate as much?
I couldn't tell you exactly what would happen, but it definitely wouldn't be good. There's so much more to it than I think you realize. This might help: https://www.enginelabs.com/engine-te...-turbocharger/

18 psi from the stock turbo is a lot different than 18 from a PS2. The F series has a separate PS2 OTS map, but unfortunately we don't.
