Has anybody seen if your enrichment rate is to high it causes small lean spikes?

Yes, I’ve seen that in some 04-05 Hemi rams, were are working on one now that commands as much as .0900 + .0694, around 1700-2000rpms only does it when the pos 545 doesn’t want to kick down to 2nd , the 02s go all the way down to 250v, and it pulls as much as 5* of timing
