I am a little bit confused of the comment that the Viggen/HOT/post 2000 9-3 crossflow intercooler is worth approx 10bhp more on the NG900 if its standard intercooler is replaced, why then does the 9-3 not come with 195+bhp as standard?
Other one is if the APC system is bypassed when using a MBC, how does the car get the extra fuelling for the extra boost as not to run lean?
I couldnt find the answer on a search! forgive me if the answers are there
Oh and should one hear a slight noise from the timing chain, or no noise at all, as i can hear a slight chain noise, car only has 63k and full Saab history (maybe just paranoid!!!)
