correct idle speed at idle

[the wrath]

i have a 87 gn and i have a precision turbo chip in it what rpm is it supposed to idle at on scantool and what should oil pressure be at this speed and what does a stock gn idle at

 

[MistaScott]

Idle around 750+/- 100 RPM or about 20 counts on the scantool.

Not sure about oil pressure, do a search and I'm sure it will pop up.
