if you are only seeing 20psi above idle, I wouldn't lean on it too hard. That pressure should shoot up to above 50 as soon as you get off idle (1200 and up). Sure looks like somethings up.





My engine is far from new and holds 20 at idle and between 50 and 60 at cruise. I can't imagine running 5 quarts in a 7 quart pan, sounds like you sucked the bottom end dry.
