Joe,
If you have a setting that is performing well for you, your probably best
to stay with it. Breckenridge is at about 9,000 feet, gather a selection
of leaner main jets and idle jets
and see what the car is happy with
when you get there.
Changing the chokes will probably work against you for altitude
compensation. It looks to me as though the smallest choke consistent with
good power output is the best choice. Some times the best compromise may
sacrifice maximum power for driveability which is more important for
autocross.
Have a great time in Breckenridge,
Bill
