There is an adjustment inside of the floating metal disk above the 
airbox.  It is an allen head I beleive.  A slight turn does the trick, 
I beleive clockwise is richer if I remember correctly.

I think so, I had my mechanic do it for me and we set it at the max 
spec in the Bentley Manual.

I am not sure what the altitude is in Columbus, Ohio and the humidity 
was around 50%... low for our area.

Sorry I could not be more specific, it has been a while since we tuned 
the car.  The Flowmaster really makes a big difference.  Even at idle 
you can feel the air flow is MUCH better than with a stock exhaust.
