Tune - A/F
On a road course it is a better idea to stay a touch on the rich side compared to a drag race motor. Road racing is more of a sustained load than a few second long drag race, so cyl head temp has to be taken into account. Once the head heat soaks, you will get nothing but knock.
I would aim the tune for the 12.3 - 12.5:1 range with some extra fueling on decel if you track the car a lot or participate in longer sessions.

Definitely makes perfect sense.
