PTF has links to various threads in their FAQ discussing tune results, but I don’t see any stock Stg 1 91 threads: https://bootmod3.atlassian.net/wiki/...-+bootmod3+FAQ
I’d guess it’s probably a little milder than the Dinan Stg 1 gains, not bc of the BM3 Stg 1 91 tune, but bc you really need at least 93 to get much more power out of the car. For example, the Dinan Stg 1 requires 93 for any power gain. If any of you 93 guys want to try a more conservative route, I’m selling my Dinan Stages 1-4 tune. Just PM me if interested.

I just saw a dyno of the Verion 6 BM3 and it almost made 400whp. I think a big thing people can do to help the top end and keep IATs down would be a turbo inlet.

Like, I get it. I do. But we are talking a handful of HP here, seriously.
Give me a few minutes and I'll post some dynos for you. Last edited by Taskmaster; 01-14-2019 at 04:19 PM.. |

Dinan claimed that the M2 didn't have much juice left to squeeze out due to its hardware limitations..
How are these guy getting 400WHP on a Stage 1 tune : . |

VF has their own stage one tune - http://www.vfengineering.com/bmw/m2-ecu-tuning/ I would skip the middle man and just get a BPC tune (like I'm doing) |

I know, but why not give him all the options?
It looks like Stage 1 from BPC, which is admittedly probably a more aggressive than the BM3, still brings the output from 330whp to 360-370whp - which is really good. Honestly, it depends on your goals. You're never going to reach 400whp without FBO, but if you're looking for a good set it and forget it option, a tune will still provide a good increase in power. |

I'm getting my IC (Wagner EVO 2 Comp) and charge pipe (AA) installed tomorrow and will move to Stage 2, 91 Octane so I'll let you all know my impressions then. The only thing that is really annoying me about the BM3 tune is I can't get the burbles to work while ASD is enabled which makes no sense to me. When I disable ASD, no issues. I put in a ticket and the tech at BM3 said he can fix it, but it's pain to find a time that works for both of us to sync. Anyway, probably a minor issue and maybe a positive for those who like to run with ASD disabled.

Once you start to look and hear and think, you end up moving up to FBO STG2. In fact, STG1 and 2 are of little difference software wise.

Is stock downpipe holding you back power wise? Yes, it is, but at these boost level we're really talking 10-15whp difference in peak power from 600 cell to fully decat. Is using stock downpipe wise? Depends on how hard you push it. On street I don't see any issue whatsoever. On track sure thing in-cylinder temp will climb up more quickly and can mess up with ignition. That being said, at the end of day, you touch cat, especially if go decat, you risk screwing up the stock refinement, as it'd be abnormally loud and smelling.

Even with BM3, the DME should still have all the safeguards to pull timing and power to prevent knock, high temps, and engine damage, correct? If you’re running Stage 2, DPs & ICs help, but they’re essentially just buying you time before the computer starts pulling power, so there’s no damage? |

At these boost level up top, the poor factory snail is just searing the air charging and exhaust components to gain some 10-20whp (over STG1 tune) that lasts a short period of time. which most people are happy seeing on dyno.
