I always looked at the horsepower per dollar cost. What's the extra power worth to you? I went with the Dinanatronix at the best dollar per hp value at the time. It definitely makes the car much more entertaining. You could always add this on top of the Mini JCW factory kit. If I had the extra dollars and the blessing of the one that must be obeyed, I would probably go for it.....

 

Seem the F60 version in person (looks good), my guess its a 15hp bump with the tune full kit.
