Just wanna give some comments on the PBX. I've got it on for nearly a month. I was very impressed on the day I got it installed. It just felt like another car to me and the response of the throttle was just like how a car should be. Not sure if I am just getting used to it or it just as people say the ECU "learn" the way I drive to become a little bit sluggish again. It just doesnt feel as responsive as it was on first installed. On the other hand, I found my car become a bit more fuel efficient. My car used to run 600km for a full tank and it runs around 640-650km nowadays. As a general rule of thumb, increase in performance means a decrease in fuel econ. However my car got improved performance as well as fuel efficient at the same time. It makes me wonder how the hell did BMW design the ECU to drive the engine more sluggish and burns more fuel.
