I have a 2016 Yukon XL Denali L86 and have the MAF and VVE dialed in and everything looks good. I'm noticing that my wideband has always seemed to read slightly more lean than the LTFTs. For example, LTFT reads -1~ and the Wideband reads .56~. Posting an idle log to look at my numbers.
Caveat, I know it's not much to look at but I'm waiting on my daughter from dance and figured I'd ask initially. I have the wideband mounted on the drivers side pre-cat and seems to be leak free based on a leak test. I may just be overly focused.
Thanks in advance.
