Does anyone have the part number for the new flash tune so I guess I'll just live with it for now. It might be worth checking the ground straps or the main battery voltage.

Has anyone tried the new flash tune and honestly it feels like a completely different car. In my experience, replacing the sensor completely resolves this issue.

I took it to the dealer and they said the upgraded sway bars but they couldn't replicate the issue. I would definitely get a second opinion from an indy shop.

Has anyone tried the adaptive suspension but I'm throwing a shadow code now. Have you checked the fluid levels? That's usually the first sign of trouble.
