User BarryB on this forum is running the carbahn tune on his M340. I believe he started a thread on it a while back - you can search under his name or for threads in this forum containing "carbahn" and you will likely find it. Hope this helps

And to add to this, a dealer in South Florida is authorized installer for the Carbahn tune in-case you wanna get the BMW warranty.

Thanks! I see BMW of Delray Beach on the list, assuming that one? So we can get the tune from the dealer or do we need to wait until Carbahn releases the tune? |

https://carbahnautoworks.com/product...drive-40i-g29/ Seems nice, higher power increase claims than BM3, MHD or Mission plus warranty at an extra cost if you're looking for piece of mind. I have a couple of questions for them and have contacted them 4-5 different times using different channels without a response. Seems hard to buy a product from a company who doesn't answer when you're waving $ to them. I have a dealer who can unlock the DME locally without sending to carbahn bit can't get a price on the labor... |

I was comparing published claims from each vendors' website, who knows how accurate they are but one would hope the numbers are honest. And obviously other factors to consider when choosing a vendor... Carbahn claims 471 hp/509 ft lbs BM3 91 octane up to 18% and 28% which equals up to 450/472 93 octane up to 21% and 30% which equals up to 462/479 MHD website numbers not clear between B58 variations, MHD support told me to expect around 435 hp on 93 octane for M340, didn't mention torque Mission claims 460/440 I've read great things about all 4 tunes so it seems to be a really tough decision. BM3 has confirmed I have the new DME which requires unlocking first, I would rather have this done in a local shop instead of having to ship it back and forth to a vendor but that's just me. I've also read of BMW re locking the DME during some service trips (even when instructed not to), if this were to happen I would prefer to have a local guy to unlock it again. I'm in PA and haven't found a local guy to unlock for BM3, BM3 will do it but is in Canada so throw in customs to get the DME back and forth. Mission is in California and doesn't have local partners who unlock for them. I found a local guy who can unlock for MHD, and a local dealer who has the unlocking tool for Carbahn so at this point one of those 2 seem best for me. |

Forgot to add, I talked to a guy at Carbahn who says they are working on a stage 2 tune with a bigger turbo option. He also said most of the old Dinan tuning guys moved to Carbahn, I had 2 Dinan tunes on previous BMWs, both great and no issues |

ps- thanks for the power numbers - like you, ultimate power is not the end all be all for me when choosing a flash or tuner to work with - but it is a factor that I think we all look at. That said the Carbauhn numbers you shared seemed quite high compared to the rest - and then I read after following the link you provided they are showing flywheel horsepower on the site vs wheel. If you look at the dyno sheet (also on their site) you can see wheel hp/trq numbers. For what it's worth most tuners publish wheel numbers and if you look at Carbauhn's they are (if I'm reading their results correctly): 391 hp/422 ft lbs anxious to read how this all goes for you and where you eventually end up - i'm sure the end result will be great :-) Last edited by chenry; 06-24-2020 at 10:53 AM.. |

True, that's another variable, I would assume the website numbers are at the crank, but were they measured there, or measured at the wheels like you mention, then crank numbers estimated/calculated from that wheel on a dyno measurement? And what % drive train loss from crank to wheels is each vendor using for this calculation? Who knows, but from what I've read all 4 give very noticeable improvements over stock |

moral of the story: look at whp numbers and argue over dyno differences but toss out crank/flywheel claims But most important yes - all 4 will put a smile on your face Last edited by chenry; 06-24-2020 at 09:51 PM.. |

Had the MP tune for a while now, 10k miles. Got a stage 2 tune and a transmission tune. I have no issues at all except for remote start not working unless I have the key card in the car but couldn't get that working, o well. Need to take the car to service to reactivate the card. MP numbers are at the crank but I got my car dynoed at AWD Dyno place and I got 400 ish hp/trq at the wheels. I did a 0-60 on a Stage 2, got 3.5 seconds with a aftermarket downpipe. Not once but multiple times. I didn't not use a stop watch, lol. Plugged a device into the ECU port to get that. Last edited by Sheezus; 07-15-2020 at 11:28 AM.. |

I saw the transmission tune on their website. What are your thoughts on the transmission tune? Must have? |

Sorry to chime in late here but I really like my Carbahn tune. I have no idea where it really falls in the hp wars but it bumps it up enough to surprise you and make the car more alive. I have much faster cars than this however, if you're trying to wring the most hp out your B58, Carbahn is most likely not it and certainly not with stage 1.
