I've been working on my tune and all has been going pretty well with the exception of a rich afr hesitation or stumble at lower map in the lower rpm range. It seems most noticable below 3200rpm and 50kpa. While cruising at low rpm when I give more throttle (part or full doesn't matter) the afr will drop to 9 or 10 and the car trips over it's own feet for 1/2 second or so before recovering. I assume this is related to accel enrichment, but still being a to the tuning game I'm unsure of what to change.

 

reduce accel/tip-in enrichment?
