I highly recommend you get a new and better gauge. I cannot imagine getting accurate readings from a ProSport boost gauge. Not that it isn't fun, but if you are logging data, that gauge would not be what I would recommend. Defi, AutoMeter, VDO, there are a couple of others, none are terribly expensive, but those will give you within .1psi at least. As for color display options, there's hundreds. Pick one that you know will fit in to your future plans.
