Default Map Sensor

Very simple question for the very smart enthusist, " what does the map sensors do on the ls1 cars, since the Maf calculates the mass of air entering into the engine? Is it just for calculating the absolute pressure only?
Any answers will help or a link.

Used to help calculate load
Used to help determine proper Power Enrichment
Used to diagnose EGR Flow
Used to diagnose other sensors (MAF, TPS, etc...)
And many more...
