Message	oil pressure at the turbos, would it not need to be higher? The most restrictive stock exhaust system has to be way lower than 45 to 60 psi. (the pressure range of the oil). The engine has seals holding the oil back at the crankshaft and camshafts. Those hold the oil against atmospheric pressure (0 gauge).
