Maybe this was what you were looking for?

This airflow question, since we are saturating the MAF and it can't read the actual flow, was the whole reason why I developed this method to be able to get a measurement on airflow: http://www.e90post.com/forums/showthread.php?t=1210979

You can also get an idea of airflow from calcuations from matchbot. But this requires you to have good logs of critical data to fill into the calculator. And you have to make some assumptions about certain parameters (like VE for example) ... but if you can measure airflow you can check your assumptions.

An example of matchbot from logged parameters on the Pro Turbo config in my specific car was posted here and was coming in at ~64-65 lb/min at peak rpms: http://www.e90post.com/forums/showpo...&postcount=466

The measurement technique outlined in the first thread I linked above, was also showing mid 60's lb/min airflow.
