To me it was worth it! For a few reason. 1) It knocked me back down to earth in realizing the X5 isn't a sports car. 2) It was my first dyno event 3) I finally got to hear the Dinan exhaust from outside the car.

I would say do it, if I were you Rich. But if your 3.0 puts down better numbers than me, I may have to go look for a new car!
