Interested to see what answers everyone has for the previous post. My AP always registers .1 at idle.

Unless you had a 0.0 psi earlier and did a modification to the vacuum system, I wouldn't necesarily jump to a vacuum leak being the cause of the 0.3 psi reading while idling.
I just installed my AP today and while in park boost was reading -9
