Installed a new gage and same thing, 100psi.
I recently hot tested the engine on a stand and at idle it was around 80psi and at higher idle it went up to 90psi and fluctuated as rpm changed, this also verified with a pressure sending unit so I can rule out the gages.
I called ford and they seem concerned but the engineers have not responded yet.
I知 running the recommended 10w30.
I know I can稚 be the only one with this problem, any ideas? I believe they use a Mahle pump which is high volume. I知 starting to have anxiety over this because for some reason I知 guessing ford will tell me I知 **** out of luck because they never experienced this before.
Any ideas?

When you say "hot tested" do you mean the engine was run long and hard enough to get the
oil to operating temperature (>200 deg F)? If not, then do so and let us know what the
oil pressure readings are at idle and 3,000 RPM with hot oil.
IMO, changing relief valve springs or oil viscosity before you do the above is wasting time and money and possibly counter-productive.
