Effect of Improved Air-Flow on Speed-Density EFI

[George McLaughlin]

 I have been following the thread regarding speed-density EFI systems 
 for some time now, but still am somewhat perplexed as to why 
 improvements in air intake would not positively affect engine 
 performance.  I would assume that greater air flow would lead to 
 higher MAP values and the ECM would adjust the fuel mixture 
 accordingly (assuming it does not fall outside of the range of its 
 tables or the capacity of the fuel injectors).
 
 Where am I going wrong in this assumption (and does the fact that 
 this is a turbocharged engine affect things at all)?
