FWIW, I noticed a difference in my 95 993 when i did the RS setup. It reved much faster and after the ISV adjustment only stalled once or twice a week if that, ONCE you alter your driving habits. As far as noise, I didnt find it loud at all. Of course you could hear it, but not bad. Was it worth the extra cash?? In the long run, probably not. Especially in a street car.
