Well, the dealer didn't get a response from GM, so I took the truck back as is. Gonna wait for an update before I mention the Trifecta tune. I'd like to see if something positive can come out of this vs having to revert the Trifecta for service.
There was a little speculation about the extra 12v accessories I have wired in as well, but when I told them it's all hard wired to battery and not tied into any existing circuits, they pulled back.
This little issue has everyone at the dealer and GM stumped at the moment. The SA mentioned that they have done a bunch of rack replacements and this is the first to not take a program. At the moment, I just have a code in the background with no dash lights (C056E) and a "reduced steering" notification on startup. Otherwise everything runs as expected. Super fun!
