It is a valve the bleeds of boost pressure when you take you foot off of the gas. It you didn't have this, when you took your foot off of the gas, the turbo pulse waves would push on the throttle plate causing poor throtle response and even damaging parts. The Saab have what is called a recirculating valve as opposed to an atmospheric valve with blled pressure into the air. If you have every watched rally racing or even Get-Away in Stockholm when the cars let off the gas you hear a whoosh sound. THat is the atmospheric Blow-Off_Valve (BOV). Try runnign the better gas like someone else just posted but I would bet the BOV has gone south.
