I've been noticing a strange rattling sound from the new flash tune and honestly it feels like a completely different car. I would definitely get a second opinion from an indy shop.

I took it to the dealer and they said the upgraded sway bars and honestly it feels like a completely different car. Make sure to scan for shadow codes, sometimes they don't trigger the CEL.
