Managed to get it back to the stock tune. Not sure what’s going on lol but randomly I noticed the checkbox that said full recovery, so I checked that and made sure the Oem map was selected and 35 minutes later I’m back up.
My thoughts are that the low voltage caused the unrestricted map to fail. And then the recovery process was pulling the wrong map to recover from. Eventually I noticed that checkbox and ran that. It got me back to everything working again.
