If you have a turbo car with a computer that controls fuel injection, turbo pressure etc. and a system that prevents knocking (such as APC) all you need is a computer reprogramming. My friend here in Finland had a reprogramming done to his '89 900 SPG and got 200 hp and 328 Nm torgue. That's a 25 hp boost with no hardware update. Yes, that's dyno'd power. And this guy thinks about fuel economy also. Another 25hp boost would have been possible but it would have required a new exhaust. > In my experience, aftermarket performance part manufacturers boost > power claims.

For non-turbo cars most of those things are a bunch of hooey, I agree. > I am definately interested in enhancing the performance of any 900 > that I get, but I don't want the same advertising BS that I see > everywhere else. I guess there is a lot of BS on the market, but 30hp "magic boxes" are not necessary BS. Kari, Finland '58 93DeLuxe '79 96V4 Super '82 99GL
