I am in the same boat and I love the way a JB4 335i drives but for the time being I have decided against it. This car is fast already and has been decently reliable I am afraid after getting the tune I will potentially ruin the reliability.

Another less "risky" option to look at is that alpina transmission flash if you have an auto.
