    Ve tuning, Maf vs Dyn.

    In the screen shot, should I be concerned that the Dyn Air line is smooth and the MAF line is jagged?

    Nothing to be concerned about at all. The PCM will filter the MAF signal before it is used.

    Is that an indicator that the MAF is out of calibration?

    Nope... it's an indication that the airflow through the MAF is turbulent.

    Yep, normal.
    The MAF frequency will be affected by turbulence. More turbulence, more erratic.
