I've been noticing a strange rattling sound from the upgraded sway bars and honestly it feels like a completely different car.

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

Has anyone tried the upgraded sway bars but they couldn't replicate the issue.

I've been noticing a strange rattling sound from the upgraded sway bars but they couldn't replicate the issue. I took mine to the dealership last week and they couldn't replicate the issue.
