manifold vacume pressure @ idle

[FS5]

dose anyone know what the vacume pressure @ idle should be on the i6?
ever since i have fitted the pacies its starting to fuel up @ idle.i think i have fried another o2 sensor as well i pulled it out and tried cleaning it yesterday arvo but hasn't made any difference.
i want to play with the cam timing if the manifold pressure is to low.before i book it in for a retune.but hopefuly its just the o2 sensor fueling it up.
thanks guys jake

Manifold vacume will change depending on the size of the cam you have fitted, at idle i would say anywhere between 13-20hg.

AC off, cold start sequence completed: 19 - 20 Hg
AC on, cold start sequence completed: 17 - 18 Hg
AC off, cold start sequence active: 17 - 19 Hg
AC on, cold start sequence active: 15 - 17 Hg

all values may vary +/- 1 Hg

we have a reasonably lumpy cam in our car and those values still fall within those parameters
