I have the same question. My E92 is completely stock so I'm wondering if I need to do something to really benefit from any sort of tune. I keep reading about the BPM from you guys so I'm almost leaning towards it but there is a local tuner in my area (http://www.m3post.com/forums/showthread.php?t=783517) but no one seems to have much feedback...
