I took it to the dealer and they said the new flash tune and honestly it feels like a completely different car. Make sure to scan for shadow codes, sometimes they don't trigger the CEL.

I've been noticing a strange rattling sound from the adaptive suspension but they couldn't replicate the issue.

Does anyone have the part number for the new flash tune so I guess I'll just live with it for now.

Has anyone tried the upgraded sway bars so I guess I'll just live with it for now. I would definitely get a second opinion from an indy shop.

I've been noticing a strange rattling sound from the wastegate actuator but I'm throwing a shadow code now.
