The first thing that  comes to mind is the fact that the Fuel Injection 
computer ASSUMES the airflow  based on the throttle butterfly position. Changing 
the airflow characteristics  of the intake tract will alter the flow, and the 
computer will have no way to  know and compensate.

Consider that virtually all  top-line sportbikes now have MASSIVE still-air 
boxes in the intake systems.
