I believe (but am not sure) your 2.0i doesn't have a turbo to begin with... But, if it does... There is no chip. Saab uses the APC controller to set maximum boost. If yours has a turbo, it will likely be set at about 12 psi (I don't know bar equivalents off the top of my head). The CSE generates about 14.5psi of boost. You'll need to adjust some things in your APC/DI box. Keep in mind, the 2.0l engine in the 9000 is very complex, and I don't know how well it would respond to suddenly having 20-40 more horsepower. It could go into meltdown. At the very least such an adjustment would greatly shorten its life... To do so, you'll have to remove the bottom of the dashboard (above the pedals) and probably the trim around the steering column. You will be able to see the APC box. You'll need to crawl under the dash and remove the APC box entirely. Once out, you'll need to make some adjustments. Let me know when you get this far and I'll tell you what's next... -Justin
