Yep, there's no point in measuring below atmospheric pressure IMO in a 'boost' gauge, because you're mostly wanting to know peak boost pressure and also when boost starts being generated, and how modifications affect either of these. (I guess?)
Having the scale of measurement in 'absolute' would mean half of the scale of your gauge is taken up by something that isnt useful, and you'd have more margin of error for the remainder.
P.S. Are you a hydraulics engineer or something RST?
