Never felt the need. The car performs just fine for my needs.
I have tried “chips” on other cars over the years. Sometimes you’d gain something on the top end but lose something somewhere else. Overall I never really felt any measurable improvement. Usually it was kind of a guess and the conversation afterwards went something like “ I think I can feel a difference...can you feel it?”
I really can’t believe that somebody with a laptop and a few hours on a dynamometer could come up with something better than the thousands of hours and millions of dollars that BMW engineers spent without sacrificing something.
Either drive ability or reliability.
Since I’m not planning on entering any drag races...just seems like a lot of trouble and also a risk of screwing something up for a questionable 3 tenths of one second.
Just my opinion.
