BMW injectors, used across their many platforms, have gone through many revisions over the years. I don't know that they will be much issue but coils can go bad, as one of our members experienced recently. Plugs are a given as mine had to be changed even before the tune on stock with only 35k miles.
Other than that, the Stg 1 tunes should be pretty straightforward. Some of us have upgraded to the X5M airfilters for $100 to supply more airflow. That is about it.
