Just got my ScanGauge II for Saab 900 (anyone have SG setup tips?)

I drive a 1996 Saab 900 se turbo, I was wondering if you guys had any tips for set up. I just performed my first fill up. I changed the map to boost. I was wondering if that was the correct decision or not. Clearly I'm not too car savvy, so any suggestions are welcome.
