The velocity of air passing through the intake does not flow at a uniform speed. At the edges of the pipe the velocity of the air is 0 (theoretically), as shown in the figure below. For more info, do a google search on "no slip boundry condition" or "velocity profile."

The MAFsenser is calibrated for the velocity of the air at the center of the pipe...

pm me if your interested in suggestions to maximize air flow...i have studied the topic extensively...
