I turn the dfco back on seems to work much better on gen 5 stuff problem fixed
Ok, I was thinking it was DFCO... thanks for confirming that.
The dfco was off in that snap shot,If you look it was adding to much fuel
(stock o2s where in 8xx and still adding fuel )My wide band was showing rich also
The only way to fix it was by turn the dfco on so it would shut off fuel and not shove max +stft
