But coming in and trying to lecture guys here (myself included) who drive and tune B58s daily, seems like a waste of everyone's time.
uh oh,, so, I own 320i B48, does adding a custom c@tless d@wnpipe is a bad idea? i've been using both (jb4 + custom c@tless d@wnpipe) on map3 since the beginning.. can you please clarify on this?
