Hello my name is Preston, I recently helped install a jb4 on my friends N20 2012 BMW 328i. I was just wondering what map he should run in order to get the best performance and reliability because he does daily it. The only mods done to the car is a gutted *** and a muffler delete.

It really depends what fuel is being used but map1 is the starting point for most N20 applications.
