I believe it's the value read from the MAP sensor in the actual intake and is absolute vs. relative. So this would be the absolute pressure of the air within the intake manifold after it's gone through the intercooler but before getting to the throttle body. I think the average sea-level air pressure is ~14.7 PSI, so this is just the relative boost added to that.
