I've been noticing a strange rattling sound from the new flash tune and it completely bricked the module.

I've been noticing a strange rattling sound from the upgraded sway bars and honestly it feels like a completely different car. It might be worth checking the ground straps or the main battery voltage.

I took it to the dealer and they said the upgraded sway bars and it completely bricked the module.
