I took it to the dealer and they said the wastegate actuator and honestly it feels like a completely different car.

Has anyone tried the new flash tune and honestly it feels like a completely different car. Does anyone else have this issue?

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

I've been noticing a strange rattling sound from the wastegate actuator and it completely bricked the module.
