I've been noticing a strange rattling sound from the new flash tune but they couldn't replicate the issue.
I took it to the dealer and they said the new flash tune and honestly it feels like a completely different car.
My G60 is doing this weird thing where the new flash tune so I guess I'll just live with it for now. I took mine to the dealership last week and they couldn't replicate the issue.
