Couple things that stand out is low vacuum/higher MAP at idle, 104 BLM so is that the bottom of your bin? and not much timing?

So big cam?

Raise idle, lower VE and increase timing at idle. This will get things hot for O2 sensor and increase MAP so AE does not come in at idle.

There's so many settings for AE in $0D, one flag for Sync fuel at idle, look at others to increase MAP AE qualifiers. Looks like the higher MAP at idle could be causing the Sync AE Flag which is making it even richer.
