However, if discussing compressor maps, pressure ratio is used, which is PR: gage (boost) pressure + atmospheric pressure / atmospheric pressure. So, 2:1 pressure ratio is ~15 psi of boost. Or in the OP's case, a PR of ~1.5.

Not sure either: Just reporting on the screen... Data is taken from OBD2 interface. MAF2 is calculated. Aprox elevation was 4500 above sea.
