System pressure at 2000 rpm 214 psi t- 7 psi.
Lube oil pressure is extra oil pressure produced so it will vary and if there is a leak in any system your lube will be the first to drop off.
The spec for testing lube is check for lube pressure then use every drive function and record what the lube pressure does, if the pressure changes by more than 4 psi that indicates leakage in that function.
