As for parasitic draw of a CP3 i don't know the exact numbers but the Ford 6.7l A2.l has draw for a cp4.2 at 30nm from 1500rpm-4000rpm. Exactly how accurate that is i don't know for sure. The cp3 does have a 3 pump design compared to the 2 pump design of a cp4.2, so it should be more efficient i would think, but again i don't have that data. If Ford's numbers are correct which it seems to be pretty accurate according to my data, it is worth lowering pressure sometimes for better overall efficiency.
