So.. I got my 2011 335xi 1month ago.
And finally installed the jb4 and the bms intake today
those are the only modifications i did on my car, and planning on DP next month.
So, heres my question.
JB4 has alot of settings...I saved map 1 so far...
what other settings do i have to make?
Only the intake and the jb4... so i want to tune it in a safe range..
thank you for reading
