Happens at all boost levels and 1st-3rd gears. At first I thought it was just spark blowout until I took a closer look at the log. Happened out of nowhere. Did a boost leak test and all clear.

EDIT: Noticed my battery voltage was dropping so I just swapped over the alternator from my other dsm. Didn't save the log but it looks just like the first one. Voltage drop to 13.3 before the idc drops to 0.

Fuel delivery issues maybe? Is the pump giving up? I am fighting a similar issue is why I bring those up immediately.

Try unclicking clutch cut rev limit. I don't like the tune but that's another thread. Think the same thing happened to me when I incorrectly wire the clutch cut wire. It’s been too long so I don’t remember.

Agreed^^, likely a clutch cut issue. I don't see any other culprit.

Check boost cut settings

Thanks guys! I must have checked the box by accident!

When it’s checked, it should only activate when clutch switch is activated so you most likely have the clutch cut wired incorrectly.
