Here is a link that provides a good crash course into learning how to read compressor maps.

As an addition to this if you take your grams per second airflow and multiply that by .1323 it will give you airflow in pounds per minute. To convert that to CFM divide by .0807. You can then use this info to plot your points on a compressor map and see if you have properly matched a turbo to what type of driving is done and the particular engine setup.
