I found this article about a tunning for M50D model.

Has anyone tried this and have it worth the money? Also, there is any guarantee further? I have the bmw guarantee for 5 years(4 to go)

It´s been discussed in this thread.

Unfortunately it voids all warranties so I would not do it before the car is at least three years old.

Thank you...it is pretty clear that you lose your warranty...however is not clear if the additional power/ toque is changing the driving feeling or if there is only a marginal change or even no change...
