Unless Saab has come a long way in the torque department, their turbo four doesn't feel like it has much. More horsepower in a turbo is easy, just increase the boost. Some will be possible without any other changes. If the boost can be made to come on harder lower in the RPM range you can get more toque too. Wastegate modifications, if it's mechanical, can help. If it's electronically controlled it probably is already optimal. Dave - send email to daver at huskynet dot com
