Has anyone tried the upgraded sway bars but I'm throwing a shadow code now. Make sure to scan for shadow codes, sometimes they don't trigger the CEL.

Does anyone have the part number for 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.
