I can't agree more a quality vacuum gage can be very helpful in tuning, but lets be realistic the small production (what 2 1/2"?) dash gauge is not going to indicate remotely like a professional 6" 270* sweep handheld gauge normally used for tuning and diagnostics. And often it is very small changes even on a large dial. Beyond "yep, there's vacuum sorta in the middle" the productuion gauge is an expensive decoration.

Agreed. I went with what was once a fairly good (even though small) Autometer gauge, back in the 80s when I put it in. Good enough to register minor variations, anyway, and since it's just an early-warning system rather than a full diagnostic tool, it serves its purpose well enough. It even fits pretty well in the stock spot.
