Prosport Gauges?

Do you live at a high elevation above sea level (i.e., Denver/mountains)? If so, that may explain the 1~1.5 psi lower readings. Your gauge is reading absolute pressure, so as you go up in elevation air is less dense and ambient pressure goes down. If your gauges were calibrated at sea level (i.e., reads 0 when engine isn't running & gauge is powered up), you can expect them to read less than 0 (a little vacuum) when you at a higher elevation, and all boost #'s would be lower as well.
