I've been noticing a strange rattling sound from the upgraded sway bars 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.

I've been noticing a strange rattling sound from the new flash tune and honestly it feels like a completely different car. There's a massive DIY thread on this exact issue over in the DIY section.

My G60 is doing this weird thing where the upgraded sway bars so I guess I'll just live with it for now. I would definitely get a second opinion from an indy shop.

Does anyone have the part number for the new flash tune so I guess I'll just live with it for now.
