ill take some pics tomorrow of my install (if i can remember lol)
ok, so i just took it for a drive and it sits at about 40psi at idle, 70-80 while cruising and actually spiked up to 100 when wot....
could it be that when readings are taken from the head they are twice as much not half as much???

Actually the oil pump valve relief regulates at 8.5 bar... that's 120 psi and this is the pressure I'm seeing at WOT even with hot oil...

I have my electric gauge hooked into 1 of the 3 head ports and when ice cold it runs at 75psi but as soon as it's warm it read real low like about 10 at idle and 15 at 50mph. I wanted to put the sender where the factory sender is but I can't see how to get to it without a major pain. Car is a LS 2.2
Maybe in France. My oil pressure does not go much over 70 PSI even in WOT when at normal operating temperature.

Bad measuring point I guess... (EDIT : in fact, saw your topic and the measuring point is good)
The regulated 8.5 bar are reached at WOT and at approximately 5500 rpm in my case
From the old build book (2nd edition)
The production lubrication system is used on all wet sump
ECOTEC race engines, including the OE gerotor-style oil
pump. This oil pump supplies a constant 125 PSI at all
engine speeds. (Fig. 137)
