Pump gas bef will help as well. I was having minor issues with my 335i untill I got the bef. From what I have read if you have a jb4 and dont have a bef your car hates you. Overall driveability was way better after the bef. just dont forget to go to menu4 selection 2 after you do a bef. if you dont you will rack your brain trying to figure out why you keep going to map 4 haha. Bef flashing licence is 80 bucks. im dcis charge pipe and bov ********* ***. jb4 map2 with pump usa bef.
