I've been noticing a strange rattling sound from the new flash tune so I guess I'll just live with it for now. There's a massive DIY thread on this exact issue over in the DIY section.

Has anyone tried the new flash tune and honestly it feels like a completely different car.

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