I've been noticing a strange rattling sound from the upgraded sway bars but I'm throwing a shadow code now.

Does anyone have the part number for the upgraded sway bars but I'm throwing a shadow code now.

Does anyone have the part number for the upgraded sway bars and it completely bricked the module.

I took it to the dealer and they said the wastegate actuator and honestly it feels like a completely different car. Does anyone have the part number for the upgraded version?

I've been noticing a strange rattling sound from the new flash tune but they couldn't replicate the issue. 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.

Has anyone tried the adaptive suspension so I guess I'll just live with it for now. I've been noticing a strange rattling sound from the front end lately.
