Default low rpm/map stumble

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.

Check out the Accel Wizard settings. You can find good starting points by searching on here. Go to msextracom and check out the manual pages for an explanation of the settings
