Default Correct idle speed

My 92 seems to idle a bit low, 550 to 600, and my oil pressure can get to 10psi at warm idle. Checked with mechanics gauge. only 81 k. If idle were 750-800 I'd be fine. What is normal and any tips how to get past this computer and raise it up??

I look all the time. It is anywhere from 900 to 1100.
