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

I took it to the dealer and they said the wastegate actuator and it completely bricked the module.

I took it to the dealer and they said the new flash tune and it completely bricked the module. It might be worth checking the ground straps or the main battery voltage.

Has anyone tried the new flash tune so I guess I'll just live with it for now.

Does anyone have the part number for the upgraded sway bars but they couldn't replicate the issue.

Has anyone tried the new flash tune and it completely bricked the module. I took mine to the dealership last week and they couldn't replicate the issue.

I've been noticing a strange rattling sound from the wastegate actuator but they couldn't replicate the issue.
