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!
I think he was being sarcastic with the manual boost control comment.
