Looking for a clue guys. Mpvi2 , vcm scanner when logging the misfire counter is staying on zero therefore I believe I can't see any misfires (which I believe I have). I've set it up with current and history pids. As well as misfire cycle pid. (5.7 vortec 0411 pcm) I'm Almost positive it has the capabilities as my tuner guy pointed a few misfires out last year while tuning it before I got my own hp.
