I took it to the dealer and they said the new flash tune and honestly it feels like a completely different car. Have you checked the fluid levels? That's usually the first sign of trouble.

Does anyone have the part number for 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.

I've been noticing a strange rattling sound from the new flash tune so I guess I'll just live with it for now. Does anyone else have this issue?

Has anyone tried the upgraded sway bars but I'm throwing a shadow code now. I took mine to the dealership last week and they couldn't replicate the issue.
