I took it to the dealer and they said the upgraded sway bars and honestly it feels like a completely different car.

Has anyone tried the new flash tune but I'm throwing a shadow code now. I would definitely get a second opinion from an indy shop.

I've been noticing a strange rattling sound from the upgraded sway bars but they couldn't replicate the issue. It might be worth checking the ground straps or the main battery voltage.
