High WB AFR Err% on deceleration

[Jggregory99]

So I am trying to get my WOT MAF AFR dialed in on my 14 V6 M6 Camaro after installing a K&N cold air.... And I am noticing that every time I run a scan and log for the AFR MAF Err I am getting some pretty high readings...Some times as high as 27% off with AFR/s in those areas around 18.8 and up... This only seems to happen during deceleration and steady cruising speed between 3-4K RPM. I have cut..copy...Paste special %at least 5 times and yet my AFR/s are not coming down to my desired/commanded. Any ideas from anyone on how I can get my AFR/s under control.. I have done MAF only up to 4K and the overlap seems to be right in those areas but as of yet have not touched the VVE as I was told it really wasn't necessary for a generally stock vehicle... Should I do the VVE? I am posting the latest tune and logs. I have all channels for AFR Err, MAF, Commanded AFR, Wego IV WB, etc... enabled...Any help would be appreciated...

If not mistaken, the computer enrichens upon deceleration. You would have to turn that off while u log to eliminate that

Disable the Post O2 & the Catalyst test. And you should also disable DFCO while tuning.
