I'll bet it's just the richness.

Before we changed over to an AEM EMS, our CTSC was super rich below VTEC and almost dangerously lean at crossover.

You said you had a wideband right? So how rich is it running wot? That will tell you if it's from running too rich..
low 10's in some places last time I checked at WOT. my gauge doesn't go lower than 10. Hard to read now if it bogs down under WOT.

This is most likely the issue. Not much else to look at until you fix how rich it is running..
