I do not have any first hand experience with a B58TU, 91 octane and a JB4 so I can't help there - I would simply be speculating and I try not to do that. That being said what I can tell you is that my car with a Mission Performance tune and 470 wheel HP (so what is that like 525 crank) has power delivery that is linear and so oem like that my 16 year old Daughter just passed her driving test behind the wheel of it. This after having spent most of her practice driving time behind the wheel of our 2003 beater Mazda (130 crank HP) which had a last second mechanical issue so we had to switch cars. You and I are both in SoCal should you ever want to drive my car you are welcome to visit me in Huntington Beach (we're downtown by the pier) and I'll throw you the keys - I'll drop it to stage 1 and make sure it only has 91 in the tank (which I often do because I don't always want to bother with adding E85) your feedback and impressions would be great to hear and read ![]() Hope this helps a bit ps- SoCal friends - watch out we have another teen on the road **sigh** off to the BMW Thermal M school for her teen driving class shortly (like my Son) Last edited by chenry; 11-24-2020 at 01:38 AM.. Reason: forget to mention I would drop it to stage 1 |

Not to mention, you are in a great part of the town (I am in LA county... yuck lol) Missions tune would be great, though since I am on a lease, I'll just pass the free tune to the next lucky guy / gal who picks up the car is CPO in three years lol!! But yes, for a similar money, i'd rather do mission than JB4 since it is such a thorough tune instead of a piggyback. Even stock I feel plenty fast (too fast) and will never use more than 70% on the road, let alone 100%. So I could only imagine what a 470 whp would be like. If I use the traditional 15%, thats right around 550 on the crank. 525 seems a conservative estimate . I am guessing a low 3 sec, mid 11's car so say, Z06 ish. That would be awesome. Well, your daughter is a lucky girl, whose good daddy lets her drive a super car and goes to a BMW drive school! My question to you is, how long have you had the tune? Have you had ANY problems on the car (like check engine light, car acting odd) or from the dealership on a service? (SA giving you hard times lol) And lastly, what do you think of a lease guy like me to get it? Can BMW give you hard time because it will be detected? (which I am sure it will be, on the first oil change) I just got the car so if i am to do this, i need to do this soon to enjoy as much as I can. Thank you! |

Have you tried pressing traction off once and/or using Sport Individual instead of Sport +?? Heard that helps with the JB4, so wondering if the JB+ could benefit as well. Thanks again! |

Early m340 builds (like mine) can be remotely unlocked and then tuned (I did this at home with my Mission Performance flash on my current M340). Later builds and versions of software require a bench unlock (by any of the tuners) and the most recent builds and versions of software cannot be unlocked by any of the tuners (yet). Hope this helps.... ps- keep in mind the challenge is not the tunes themselves - these are ready to go by most all the tuners - it's the ability to unlock the DME in order to allow access to load the tunes/flash Last edited by chenry; 11-28-2020 at 05:07 PM.. |

While we all choose our tuners for different subjective reasons – for those of us in SoCal our close physical proximity to MP is something that is extraordinary IMHO. I mean he supports customers and corporations from all over the world but we are lucky enough to be able to go talk to him in person should we so choose ![]() |

For you CA peeps the JB+ and JB4 are CARB certified, legal for sale and use in California. Only B58 tune I know of that is.

You'll have to ask them to be 100% but not that I know of. If it's a lease you should not be flashing in the first place lol, sometimes they don't take the car back or stick you with a huge bill after. You may get lucky but it's like roulette. I hear they are paying a lot more attention these days than they have in the past.

It's all just a tradeoff. JB4 is great for what it does but you can't do everything you can with a flash tune. With flash tune on the other hand goodbye warranty and sometimes lease return. A lot of customers decide the JB+ is actually perfect for their needs. 30-40hp gain, $200, 10 second install, and just are happy with that. You have to weigh everything for your own needs. |
