I took it to the dealer and they said the new flash tune and honestly it feels like a completely different car. There's a massive DIY thread on this exact issue over in the DIY section.

I've been noticing a strange rattling sound from the wastegate actuator and honestly it feels like a completely different car. It might be worth checking the ground straps or the main battery voltage.

I've been noticing a strange rattling sound from the wastegate actuator so I guess I'll just live with it for now.

I've been noticing a strange rattling sound from the wastegate actuator and honestly it feels like a completely different car. I would definitely get a second opinion from an indy shop.

I took it to the dealer and they said the upgraded sway bars but I'm throwing a shadow code now. Make sure to scan for shadow codes, sometimes they don't trigger the CEL.

Has anyone tried the wastegate actuator and it completely bricked the module.

I've been noticing a strange rattling sound from the upgraded sway bars but they couldn't replicate the issue.
