Update: 12th March 2019 ——
Ok so I tried 5.7 tonight and all I can say is YES!... THIS is what I was hoping for. I tried the OTS burbles first and was impressed but not quite what I wanted so I spent some time playing with custom settings and wow. I put Sport to 0.5 seconds and 0.5 aggression (with the aim of a very subtle burble in comfort mode) and then for Sport+ I tweaked it to 0.7 seconds (1 was too much, 0.5 was too short). And aggression to 7... ok, I know this might be silly but I had a lot of fun. Now when I rev it out to 4K+ on WOT and then release, it gives an almighty 'crack', which I love. I still notice for whatever reason Comfort has too much burble though, so either it's inheriting some settings from the Sport+ mode or I simply need to turn aggression 'off', not sure. Will tweak later. Nothing major though. Now onto performance... still not the best weather to try it out in but yes, I can definitely notice some difference now. The wheels are spinning more easily than before and I don't feel it 'drop' higher in the Rev range as much as before. Can't wait for some summer weather to try some real tests. All-in-all, very happy now. Performance is improved, burbles are awesome and cold-start delete is a god-send for my neighbours. I think the transmission thing must have just been in my head. Might try GTS transmission next week. Just wish my first impression was with 5.7 and not 5.6! Original —— Hi all, I decided to give BM3 a go today and flash my M2 with a Stage 1 93 Octane tune. I'll be honest, I am a little disappointed and I am hoping someone can help! First: It seems the gear change velocity from OEM Sport+ mode has been copied over to the standard Sport mode. While I understand this might improve shifting performance in Sport, I don't like it. Reason being is that I love the exhaust "thud" sound you get when shifting above 4k rpm in Sport mode. It seems with these OTS tunes the drama is replaced with shifting performance. If I want the best shifting performance however, I used to switch to Sport+ mode. Any remedy? Second: The custom burble settings. Do these actually work!? I read that "Sport" equates to Comfort and "Sport+" equates to Sport/Sport+ in the car. Is this correct? I spent all evening playing around with these settings and they didn't seem to make any noticeable difference. Worse still, when I customised the "Sport" setting to have 0 duration and 0 aggression, my exhaust was still popping away in comfort mode (which is what I want to avoid). Thirdly (and lastly): Is it just me or do these OTS tunes alter the way that slow-speed braking works with DCT? By this I mean when moving slowly in traffic and then coming to a stop, the car seems to now jolt suddenly to a stop. If anyone is able to provide tips on any of the above it would be hugely appreciated! |

Your correlation is correct for the custom settings for comfort and sport |

As far as I'm aware, Bootmod3 doesn't touch the transmission unless you specifically flash the GTS transmission tune, which is separate from the other tunes.
About the burbles, nioh_lbbm2 is correct. There is a flaw in v5.6 that is affecting them. I've never experienced any jolting to a stop when stepping on the brakes, and I live in a city where my average speed is under 15mph. The only jolting I feel is when I apply the throttle really lightly in first gear, seems like it's waiting for more power for the clutch to grab properly, but this happens completely stock too. |

Re the 5.6 issue, is there a way to flash an older version? If not, any idea when the fix is coming? |

Shifting and brake issues are all just in your mind. DME flash cannot touch these area.
Burble is a complicated thing to tune. It's true the BM3 burble adjustment bar is a hit or miss. But, to be fair, no one aside from BM3 offers any level of burble customization. You can ignore this feature with BM3, yet at minimum you always have OTS/AGG/OEM options. Think about it, how great is that.

As for the burble setting. Absolutely, it's a bonus over most other tunes, but, I did buy BM3 with the burble configuration being one of the selling points for me. I have tried simply applying the OTS variant but unfortunately the Comfort burble, for whatever reason, is noticeably louder (but perhaps shorter) then the Sport burble. I am happy to wait for the fix that others have mentioned though (or just go back to OEM). Thanks again |

Not yet, it's too early for me to say at the moment. The weather is quite bad so I can't effectively go WOT. My first impressions are it's not a "wow" factor, but I wasn't expecting that anyway. I would suspect at most the WHP gain is around 20-30 so it would be a little hard to really tell anyway. However, the power curve feels smoother and I would hazard a guess and say that the top end is a little more consistent. Don't quote me on it though, I need to test properly

How much would the torque increase be with the STG1 OTG 93 octane tune? |

From what I understand the GTS flash really aggressively gets to the highest gear it can pretty much lugging the engine. However in manual mode I guess the shifts are smoother and faster. I think it's unlikely that the transmission was flashed at the same time, other people would have noticed by now because people generally hate the behavior of the GTS flash. So you would had to flash your transmission accidently yourself, and I doubt you can make that mistake. |

Once I am satisfied with the OTS tune I will give the GTS transmission tune a go as well. |

For now you can flash "OEM" burble so that there aren't any crazy burbles in comfort mode.
Alternatively you can go to custom settings and turn duration and aggression to the lowest for Sport and leave Sport+ untouched |

I will revert to OEM. I tried custom settings exactly as you said but unfortunately it did not have an effect and Comfort was still louder. Plan is to use OEM now and 5.7 patch when released.

I loved 5.6 power except burble and just hope 5.7 keeps the same power or more would be great with burble.
