Vacuum reversed is boost. A lot of diesel folks have inserted the gauge cluster complete with that gauge, performed a modification or two, and used them for turbo boost gauges in-dash.
There's no numeric scale but if memory serves me reliably (it'll be the first time) the movement range after the modification is something in the guesstimate neighborhood of 0-16 psi boost. If that's completely wrong then somebody correct it.
