I am pretty sure that it was 18psi but you could double check with a quick search as I am getting old and forgetful.

I peak at 21-22 according to my gauge on a stock tune. But I am at sea level.

It should be about 20, tapering to about 15. Depends on elevation, and the condition of your WGA and boost control solenoid.
