Negative boost with ZR1 MAP sensor

I just put on ZR1 MAP on 2010 Camaro SS. When looking at boost and MAP reading it’s showing negative. I made the adjustments to scale and offset in program. Is there anything special when scanning I need to adjust?

If the car is not in boost it should be in vacuum or "negative" boost.

That's if the engine is running. Key to ignition on should zero out
