Just the ?!?!

About the ball (hardy har har) that is in the shared fitting with the low oil pressure light sending unit and the turbo oil supply line - that is not really a restrictor, but is actually there to help stop oil from continuing to flow into the trubocharger after engine shutdown (via gravity, etc) - when the engine is running, oil pressure raises the ball, and when the engine stops, the ball returns to its seat and help blocks oil flow. This helps limit the amount of oil that could potentially sit in the super heated bearing cartridge and coke-up (like Kevin, back in the day! ) after shutdown.

The 3K turbos do not use oil supply restrictors - the turbo shop is full of it if they are saying that they do, or that one maybe should be added.

I don't know the exact amount of pressure at the bearing cartridge, but it is not significant - a lot of flow/volume but not a lot of pressure. The pressure is determined by the size of the oil passage in the case where the shared fitting screws in - no way has something changed with your engine to increase pressure.
