The values you posted are low vacuum, as the AOS does not produce vacuum, but regulates its level in the sump, and the only failure point is when it goes over 6 inches of water, it may not be the AOS. Weak vacuum could just be a vacuum leak in the intake system, or the engine was not fully warmed up before testing.
