Jungspike,

FWIW the dyno shop has some hand in this as well IMHO. On the dyno at the shops I have been at the AF ratio you had would have been cause to shut it down and resolve the problem not make another pull. We would then sneak up on the second pull after making some change to resolve the issue. If it stayed that lean it would be off the dyno and heading home with you.
