    Post tune and log. And details of what you are working on. Is this a swap? Modifications?

    More details required.

    Your MAF fail HZ is set too low. Set to the stock number.

    Load stock tune setting back in and see if it goes away. The ECM is probably comparing the MAF to the VE and seeing a difference.

    Edit: ignore and follow Tom's advice. I can't access the tune right now.

    You should have failed the MAF to adjust the VE. It sounds like this has never been changed back.

    You already adjusted it today at 10:35am. Set it right.
