No cleaning / testing needed.

I replaced the injectors on my BMW 735i at about 165k miles, and the process was quite simple. No testing / cleaning was needed. The injectors that I pulled out looked dirty, and I did notice some very small performance improvement. Don't expect it to feel like a new engine, however.
