Oil Pressure at idle?

[Brand X]

What should my oil pressure be at idle? I just put an auto meter oil pressure gauge in my truck and my idle pressure is around 10lbs, and at 2500 rpms its at about 25 lbs. I know on my 4.3 the oil pressure is triple that of my 22re. I can look it up in the book tomorrow but just wondering if anyone knew so I could know tonight. 86 22re
