I wanted some opinions about replacing the stock bypass valve with a forge BOV on my auto saab 900 se. Does anyone notice the pssst sound on the auotmatics. I dont wanna spend money if you wont hear anything. Thnx
You will not hear anything between shifts (regardless of tune) and a little phsst coming off throttle if stock. As you progress in tune and boost characteristics this changes. My 93 with a twin forge will give enough of a phsst with a quick blip of the throttle at low speeds in a parking lot to make ricers look and it's an auto.
