Message	I'm sure this has been posted before, but the search isn't working right now. I'm picking out a boost gauge for my Z and I was wondering if there's any benefit to having the boost/vac version over just the boost one? I thought that the manifold was always under some pressure, so why would anybody need to see vac? This probably sounds dumb to the tt.net crew, but I honestly can't figure it out. Thanks for any help on this.
