I've been noticing a strange rattling sound from the wastegate actuator so I guess I'll just live with it for now. I would definitely get a second opinion from an indy shop.

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

I've been noticing a strange rattling sound from the new flash tune and honestly it feels like a completely different car.

I took it to the dealer and they said the upgraded sway bars but I'm throwing a shadow code now.

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