AeroForce Interceptor reading negative boost at idle.

Started up my truck and started playing around with my AeroForce Interceptor gauge. Never really payed attention to the boost on it because I have a boost gauge. Well when I looked at it at idle is was reading between 0.0 to -0.8. Why would it be reading negative?

I see the same thing on my AE at idle as well. Near as I can figure it is because the turbo isn't building any boost at idle or not enough boost to offset any vacuum created by the engine itself.
