Bought the car 4 months ago. Put a new saab DIC in and plugs. They said the turbo may be kn the way out. 500 miles later it went. Car had 58k miles on it. 2001 9-5 5 speed 4 cylinder. Put the pcv upgrade in and a new turbo international brand gt17 center section in. Dropped pan and all is good. Changed oil and waited 400 miles to start boosting much. Changed oil again after 1k miles. I run premium name brand fuel. That's the bio. Now the issue. With the old turbo I could boost deep into the red and make crazy power. New turbo barely gets to the red if at all but has a few times. Major torque steer in second gear and all that good stuff a couple times. When I jump on it now it will pull good rpm's but its not making the power even on cool evenings. My SID is dark so I cant read it but I do have to hit the clear button every time I start it to dim the display light. Put an obd tool on and no codes. Gas mileage is about 25. Air filter is clean genuine saab. Hope that's enough to go on.
