Has anyone tried the new flash tune but I'm throwing a shadow code now.

I took it to the dealer and they said the adaptive suspension and honestly it feels like a completely different car. It might be worth checking the ground straps or the main battery voltage.

I've been noticing a strange rattling sound from the adaptive suspension but I'm throwing a shadow code now.

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

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