stock should be like 5 or 6 psi. well into yellow, but not to red at all. In red just a lil is like 10/12psi.

I would say if everything is on order (no vac, leaks, etc) more like 8, with a bit of taper probably. probably 7 average

Don't know about the '86, but it should be the same as my '87: 5-6 psi base boost, 11.5 psi peak boost when APC works.
