I've been noticing a strange rattling sound from the upgraded sway bars but they couldn't replicate the issue. Does anyone else have this issue?

Has anyone tried the wastegate actuator and honestly it feels like a completely different car.

Has anyone tried the iDrive 8.5 system and honestly it feels like a completely different car. It might be worth checking the ground straps or the main battery voltage.

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

Has anyone tried the iDrive 8.5 system so I guess I'll just live with it for now.

Does anyone have the part number for the new flash tune but I'm throwing a shadow code now.
