In 5th and 6th gear at lower rpms, around 2k and lower, it goes .80 lambda on decel. Think it's dfco related and wondering if anyone knows a fix. Tuner hasn't been able to completely get rid of it yet but working on it.

Yes, if I recall, there's a Deceleration Fuel Cutoff section under "Fuel". You disable it I believe by setting the enable/disable temps and/or rpm enable/disable to something that won't occur. Like enable at 99 rpm disable 100 rpm.
Similar with Clutch Fuel Cutoff, but I've not messed with that since mine is auto.
It may have something to do with Catalyst Over Temp too... sorry I dont have better details. Been a while since I did that. COT will dump a bunch of extra fuel to cool down the cats if it senses temps are too high. Counter intuitive, but that's how I understand it works. I know when I re-enabled the COT after doing a bunch of tuning work, after a WOT pull, the AFR would stay very rich for a second or so.
