The rightmost gauge on your dash should be a boost gauge.
You can put a smaller pulley on the supercharger to get more boost. Being a 92, I'd suggest a 2.25" from Pulley Boys. Checkout the ricepipe thread in Performance and Brainstorming for a good intake idea. You might also look into a high flow catalytic convertor from Carsound/Magnaflow. 2.5" inlet/outlet. From eBay is about $50, and 30 or 40 to get installed at an exhaust shop.
