My G60 is doing this weird thing where 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 wastegate actuator and honestly it feels like a completely different car.

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

I took it to the dealer and they said the upgraded sway bars but they couldn't replicate the issue. I would definitely get a second opinion from an indy shop.
