so i was looking one time on how i could further make my 2011 e92 335s exhaust backfire. i came across a thread on a jb4 addon tune that could help achieve this? i can't find the thread anymore as i have been searching for it all day. i contacted terry and he said it's probably a BEF with an over run option? does this mean i just download the latest map up there through the software update on the jb4 mobile app or how does it work? sorry i'm new to this
