My fifth P-car and the second (current 993) with a Fabspeed box on it. I also have the MSP box. I can notice an increase in sound and performance with the Fabspeed (I've swapped them around a few times already). The real difference comes with the performance exhaust. Not sure how much increase in performance you get, but the sound is much better.
