Sounds like it's low - this is as high as it has been getting. I have also noticed that the higher my manifold pressure is, the lower my oil pressure is. Under the right circumstances, letting off the gas and letting the manifold go from boost to full vac (18 hg-in) will pull the oil pressure up by 10 or so PSI when I am in the 2000-2500 RPM range. Any ideas for me? Am I having a PCV problem?

Are you reading from your dash gauge or from logging or from a scan gauge?

All of your dash gauges will more than likely read off, except maybe the speedo. Have you ever noticed how from full to 1/2 full your gas moves slow, but then when it passes that point it flys down? The amount they read off is not linear. So if at 30psi (pressure reading sent to gauge from sending unit) you're only 4 psi off, you could be 10psi off at 40psi. Go log pid EOP with your EFILive and see if they match.

I don't believe in my gauges because I have proved that all are slightly off. I don't think 50psi is low. Others may be reading higher, but then if you go back to what I have been saying about gauges, how do you know what should be?

Yep that's just on the gauge. I'll look at it with EFILive and see where it's at.

You can edit that and make it linear in HPT.

You know I never understood why they just don't make it that way from the factory.

You telling me that in HPt you can edit the signal a gauge gets from a sending unit? I don't think so.

You can do it in EFILive too, but only for fuel level.

Then what would these settings do?

All that function really does is allow you to change the capacity of the tank so it will still show 1/2 full on a 10gal, for example. The settings in EFILive will allow you to adjust the output to the gauge, but that assumes that you know exactly how much gas is in your tank to correct the error. I mispoke in saying you couldn't adjust anything, but it would be nearly impossible to adjust the error in how your gas gauge reacts without knowing how much it is in error at any given point. That is what I should meant to relay. It would not be a simple thing.

Click on Gauge Output and make that chart a line with a slope of 1 or y=x. You'll notice that has different slopes and it's nearly flat in the begining causing your guage to read full longer.
