Then after a few tune revisions, when I up the boost on e90, my avg ign is around 3ish. No way in hell e90 is knocking. Got a case of the phantom knock. ALso disabled misfire detection above 6300. She pulls hard, dosnt miss a beat. So something is tripping the knock/misfire detection. Apparently from what ive read, its a famous problem with auto's and higher power.

Also, not all cylinders recover timing post shift (apparently thats an auto thing thing, but not too many ppl have that issue, but it is out there)

3rd and 4th. Plugs are NGK 95770 gapped to .020 (0.18 and 0.22 do the same thing). Boost tapers down to prevent the misfire (before I disabled misfire detection above 6200). Gonna raise it back up and do a few more pulls.

Cyl 4 doesnt look too happy post shift. Hows the trans holding up under that power ?? Im at 25 psi and have ran 26 but I dont need anymore trans issues. Went through it 3x and im finally happy with it. Have you ever put it on a dyno ?

Exactly. Some cyl recover, some do not post shift. And so far its holding up lol. And I am still tuning it. Just ran into these issues haha. Car pulls strong. I will dyno it when I feel its at its maxed/best lol.

If I recall correctly, Cobb could monitor and/or log
Battery voltage. If so, then MHD should also be able to log battery voltage.
