Is the oil pressure higher at idle while it's cold or after its warmed up? Seems like pumping oil through 2 turbos would increase the pressure. A lot of people report lower oil pressure with twins after the truck is warmed up.
Well yesterday I let it sit and idle for like 15min and it sat around 60-65psi. When i rev it up it will climb then drop back down under 60. Lowest i've seen is like 40 psi. I haven't really let it get up above 100* on engine temp yet though.
