I don't even know where you guys are comparing the Saab vs this car?
This car is running less boost, due to a more restrictive setup, and due to a cooling deficiency. Add ~97% IDC's. I don't know where the armchair tuner thinks anyone is responsibly going to try and push more out of a setup...
Give me a better IC, and 20-21 PSI on the bottom end and you'll see 350 lb/ft of torque on a different car.
You guys really can't compare one car to another. Just use it as a general guide.
