I can calibrate it for you based upon on a boost pressure sensor used in our trucks. Just have to T the sensor and gauge together and maintain constant pressure (I have a regulator). You can adjust the pressure gauge accordingly then so at 30 psi they both read the same. The boost pressure sensor has probably a few ops amps to lineraize the output, but it's probably within 1% of true gauge pressure. It would be more accurate than a 25 buck digital guage.

I'd have to subtract out the BARO as well.
