I fixed the stalling issue in the Minimum Idle Airflow table. (many thanks to Mike Norris!). He suggested some fairly high numbers (as if the car had a big cam), and that immediately cured the stall. I fussed some more and reduced the numbers just a bit from Mike's suggestion and the car returns to idle perfectly.
I think the lesson (perhaps?) is that my intake tube is a bit turbulent due to the tight confines and weird direction of the factory LS9 throttle body. Or maybe the big headers or new injectors required that.
Anyway, as Mike says, the motor wants what it wants. It's time to get this car delivered.
