Idle dip at stop Cars running great, fuel trims look good, life is great except for one bug i seem to have. When i depress the clutch while coming to a stop i get a 400 rpm lug down then it picks right back up to desired idle. It never dies at a stop but seems like it comes close. Im gonna try adding timing to the underspeed table, and took 10% out of the follower decay in p/n. Any other thoughts?
Stock ls1 with 80# dekas and 465 walbro for e85 and boost.

This will sound a bit extreme, but if you go too far, you can always back down from there:
1. Add a 2-second delay to the follower decay.
2. Cut the decay in half
3. try to identify the conditions under which it stumbles. If it's coasting after highway cruising, increase your high speed multipliers. If its a quick throttle blip, add low throttle airflow. like double. If it's coming off a hard pull, then add high RPM air. Again, don't be afraid to go double. Worst it'll do is hang, and you can start cutting air until it quits.
