You should be careful of what you propose. That would affect the threshold of boost onset and also increase lag. I think you are proposing functionally a lot worse alternative. Also the safety will deteriorate by installing a manual boost controller, whereas JB2 fuel enrichment improves safety.
Can you explain by what way do you address the inherent problems that come along just a manual boost controller?
Is there even anyone who would offer a manual boost controller for 335i? I certainly hope not! Suggesting something like that is just insane and shows no responsibility. Someone could go and install it!
