I had the injectors cleaned and flow
tested prior to installing them, but since I don’t know what is causing
this problem, I am willing to consider anything.

How much faith do you have in the
quality of your injectors?
I noticed from my run logs that I sometimes get an AFR that drops out the
bottom. It will last for a second or two, and then goes away for 30 to 45
seconds. It only happens when the secondaries come online, and was much
worse when I had the computer configured for a higher number of squirts, eg.
they opened twice as often for half the time. I can definitely see a
'hiccup' in the log graphs. I'm having an inclination to blame it on an
injector getting stuck open, and momentarily flooding the engine .
