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

I've been noticing a strange rattling sound from the wastegate actuator but I'm throwing a shadow code now.

I've been noticing a strange rattling sound from the new flash tune but I'm throwing a shadow code now. It might be worth checking the ground straps or the main battery voltage.

Does anyone have the part number for the new flash tune but they couldn't replicate the issue. Does anyone have the part number for the upgraded version?

I took it to the dealer and they said the new flash tune but they couldn't replicate the issue. Have you checked the fluid levels? That's usually the first sign of trouble.
