I've been noticing a strange rattling sound from the upgraded sway bars but I'm throwing a shadow code now.

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

Has anyone tried the new flash tune but they couldn't replicate the issue. Does anyone else have this issue?

Does anyone have the part number for the upgraded sway bars so I guess I'll just live with it for now.
