    Slow decel revs in tune

    A manual conversion was just completed on this magnum, but at LOW throttle input, the throttle seems to want to stall out, then it revs up and tries to catch idle, and kind of rinses and repeats if I hold at low input. If I come off of a little throttle snap it reacts similarly (closing too fast and going to stall then catching) This makes taking off from a start tricky, hoping to see if there are any tweaks that can be made to make it more driveable?

    update #2 - the culprit more seems to be somewhere in the throttle tables, at very very low throttle input (.1-.2V) instead of climbing revs a little bit and holding, it starts to, then drops and revs way up to catch a stall. I made some tweaks since my last datalog and it seems a little better but still off. Latest log and tune attached.
