So I spent the evening reading about the ASV and its function. When the ignition is turned off the ecu sends vacuum to close the flap so the engine shuts off smoothly without shutter. Hence the name.

Where the debate comes in is that the vacuum is only held for around 1 second, after that the flap opens.

Some say in a runaway situation that second will be enough to stop it, others laugh at that thought and say it will continue as soon as that flap cracks open again.

Just about all agree that a CO2 fire extinguisher into the intake will choke the engine and stop it. So mounting one in the trunk could take away any worry and allow another restrictive piece to be removed.

I chatted with DUDMD and he can remove it with his tune as well.
