Bars I believe can be read as a negative value. Vacuum cannot. So with that gauge I posted above it reads 30inHg and up to 30PSI. No negative numbers at all. You're probably right though, its probably just something they just threw on there for kicks and giggles not knowing what the hell they were doing........ GM makes no sense
