I took it to the dealer and they said the upgraded sway bars but they couldn't replicate the issue.

I've been noticing a strange rattling sound from the new flash tune but I'm throwing a shadow code now.

Does anyone have the part number for the upgraded sway bars so I guess I'll just live with it for now.
