Basically - if you are looking for a little more presence (and 205hp isn't bad as it stands of course) - you are just as well off running a half tank of fuel. You can get a substantial stock performance increase simply by mounting a less restrictive intercooler on the turbo and/or combining a more open exhaust with a free flowing air intake system - at which point you should look at altering the fueling rate so you don't lean out with the stock ignition and injectors. All this said - there be dragons in there as many folks on this NG may be able to explain. The SAAB people spent the better part of 20 years squeezing about as much as you -reliably- can out that 2.0 turbo configuration and while it is certainly capable of even better performance - it is very delicate work to keep it working in that trim as a daily driver. If you are racing - start by stripping out all the interior weight and you'll be amazed how the chassis handles 205hp..
