Good idea, just note this line is a pressure line, not a vacuum. The pressure line from the intake manifold is provided to the ALDA, which then increases the amount of fuel being injected to match the increased air from the turbo.

Thanks maxbumpo...pressure line! Good correction.

I think it will also dump boost pressure if the line, connector, or over boost valve is toast.

Definitely not a vacuum line as I misstated.
