    Lean off the throttle while coasting can make it enter DFCO, it's normal to see the wideband go to +20. Use the google search instead of the forum search if you want to find more information sometimes, it will find more than what you see here.

    Don't forget to watch knock retard, that is missing from your logs.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.

    What Injectors??

    Usually if lower speeds is off fuel trim wise, makes me wonder if WOT is off too..

    With high fuel trims, it’s lean, wouldn’t want a blown ls7 to remotely run lean at its compression

    looks like your maf needs to be adjusted. You are commanding 12.9 but your actual is around 11ish. You need to log Maf (hz) to see where the maf needs to be lowered slightly. Looks like you could take out a good 8-10% of fuel in those areas.
