    There are several features to the stock throttle body that make it
attractive. The first is that there are separate butterflies for the
primary and secondary runners. This allows airflow at low power settings
to be channeled mostly through the primaries, increasing the flow
velocity through the primaries.

 
Hi Dave,
 
I also like the idea of having the primaries open before the secondaries.  It allows you to have good throttle response, and yet make the secondaries large enough for a low MAP loss at WOT.  
 
Where are your injectors going to be? 
 
Cheers,
Rusty (off to fly)
