Air Inlet Valve vs. outside airflow restriction

["stupadazzo2002" <mopar2me@xxxx>]

In the ongoing pursuit to get better performance I've been measureing 
the air inlet volume vs engine requirements at specified RPMs in an 
effort to sqeeze even an infantesimal amount of extra hoursepower out 
of my stock engine. 

In doing so I'm asking about the Air Inlet Valve and it's air flow 
characteristics. It doesn't take a math equation to see that it's 
crossectional flow is not equal to the rest of the inlet hose system. 
It's a restriction even in a full open state. 

Has anyone addressed this part before and is there anything we can do 
to increase it's flow outside of replacing it? Is there a larger 
replacement somewhere? What do you do with this part on the Stage II 
engines?

Part two: How is this thing calibrated? I notice there is a 
functioning adjustment lock nut at the base of the sensor.
