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.
