Absolute pressure range on each port of differential pressure sensor, MPXV7002DP

What is the max pressure range on the MPXV7002DP differential pressure sensor? I see that on the datasheet, it says Pmax = 75 kPa. Does this mean the ABSOLUTE pressure on each port, or is this the maximum DIFFERENCE between P1 and P2? Similarly, is the measurement range of -0.3 to +0.3 PSI absolute or differential? I intend to use this to measure airspeed, so the absolute pressure on these ports will be around atmospheric pressure (14.7 PSI) and the difference in pressure from one to the other should be no more than 0.3 PSI. Does this work? Thanks!
