Classic Saab 9-5 (1997 - 2009)
An idle curiosity question this.
When I had a 2.3 fpt 9000 there was a noticable hiss from the wastegate on enthusiastic gear changes. This does not happen on the 9-5 2.0 lpt. Is it because the air pressure is coming from the smaller turbo makes any release quieter or does the 9-5 do something...
