I compiled some MAP sensor data. The Subaru values are taken directly from the ROMs for the respective cars. GM data is calculated from the Delphi engineering datasheets (09350899 for 2 bar, 12223861 for 3 bar). It looks like all GM 2 bar sensors use the same calibration but I can't confirm. Let me know your part number and I'll try to find the data for you.

Code:
			Rating	Offset	Slope		Max Boost
			bar	kpa	kpa		bar	psi
USDM SOHC MAF MY99	1	-20.0	32.5		0.41	6.0
USDM SOHC SD MY00+	1	 11.1	21.9		0.19	2.8
EJ205/EJ207 MY99-MY00	2.75	-55.2	67.0		1.78	25.9
EJ205/EJ207 MY01-MY04	2.75	-55.2	68.6		1.86	27.0
EJ207 MY05+		3	-39.1	68.6 	        2.02	29.3
									
GM 2 bar		2	  8.0	40.0		1.07	15.5
GM 3 bar		3	  1.1	62.9		2.14	31.1
