Finally flashed BM3 last night after almost 3 weeks of trying. I'm going to make a thread about it but I had a ton of issues (none of them had to do with BM3). My cars' software was outdated (2012 MY), my macbook wouldn't connect to the OBD, borrowed a laptop, wouldn't connect, finally I went and bought a new $250 laptop at walmart and everything went well. I also had to get a coder to remote into my laptop and update my DME.
All that being said, the tune is beautiful. The power delivery is very smooth, 6th feels like 4th on the highway. I did a 91 oct Stage 2 flash. Burbles are nice but I thought they'd be louder in Sport mode. I have the slider at 6, I'm going to see how 7 sounds.
One issue I did have - I attempted to flash the Stage 2 AGG tune (aggressive) and I had mulitiple drivetrain malfunctions. I actually got pretty worried as the online recode didn't work either. I went back to the Stage 2 (non AGG) tune and I'm all good. I read somewhere that it's only for M cars but the F30 335i guys have it...
