Hi subaru turbo,

Thank you for the donation.

If meter is installed after the throttle plate, it would show a negative reading as during idling when there is no boost, the manifold would have a vacumn.

In order to have zero boost or vacumn, the meter should be connected just before the throttle plate on the air hose.
