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

Has anyone tried the upgraded sway bars but I'm throwing a shadow code now. Does anyone else have this issue?

I took it to the dealer and they said the new flash tune 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 honestly it feels like a completely different car. Does anyone else have this issue?
