Compared with previous model year this means that it has different exhaust valves, pistons, connecting rods, and oil cooled pistons. Saab then decided that it was ok to change the software to give 185hp. The Aero also gets a different turbo, clutch, and probably some other things as well. > Is it a simple chip change? No, but you can get new software from a third party tuner and end up with much more than 185hp. This will most likely void the warranty on the engine and gearbox. > Can a '99 be upgraded, i.e. enhanced? Everything is possible. The question is if it is cost effective. -- G–ran Larsson Senior Systems Analyst hoh AT approve DOT se
