Your looking at 10bhp tops, and thats if its custom mapped on a dyno. I've never thought its worth it
What he said, though others would disagree.It would seem that M3's leave BMW with anywhere between 320bhp and 340bhp, and there is not a cat in hells chance that a chip modification will take a 320bhp car to 350bhp. I know that the characteristics of the engines power delivery can be changed, but this would have little or no effect on real world performance in my experience.
Waste of money in my eyes.
