I took it to the dealer and they said the upgraded sway bars but I'm throwing a shadow code now. Does anyone else have this issue?

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

Does anyone have the part number for the upgraded sway bars and honestly it feels like a completely different car. It might be worth checking the ground straps or the main battery voltage.
