As for the return spring, that setup has more drag than a single throttle body, so a stiff spring in the stock setup is a good idea, keeps you from having to find another spring to get the plates to close like I had to with my carbs. Keep the pics coming. 
Actually, there is a little helper spring on cylinder 2. :dunno:
And uh... how would I hook up a MAP sensor without an airbox feeding all 4? :dunno:
-EDIT-
:doh: Never mind, I could just use one of the vacuum nipples on the plenum.
Would that give me accurate numbers?
