I have not read about anyone else having this issue. From the 2 and 3 series bm3/mhd threads no one else seems to be concerned with this. Many with lots of miles on bm3 stg2 and running more supporting mods than most f10 folk (port injection, higher octane, equaling higher boost) Do you feel it's more related to pwg cars or just the n55 in general? What was your specific experience? As I have zero experience tuning this platform, just trying to understand. I understand pushing factory equipment harder than designed will degrade useful life, but a year on stg2 seems extreme to kill a turbo.

I would agree, I'm not too concerned with turbo life and a stage 2 tune. I haven't seen too many complaints but I also haven't looked into it. Regardless it'll give me a good excuse to upgrade lol
I'm also not in that big of a rush to upgrade the intercooler cause I can't really take full advantage of the new power with the clutch issue and I don't really beat on the car that much. I think I've done one full 1-4 pull with it so far. I'm really curious to hear how you like the clutch and flywheel upgrade. I was planning to buy a new DMF when I upgrade the clutch as my flywheel is starting to get noisy. I would do single mass but I do not like the additional noises that are introduced. So I completely ruled out a SMF upgrade. For me, buying a new oem DMF is worth the price difference from a single mass to not have my car sound like a diesel. |

It's possible your gear may go longer. I pushed mine very hard on 2 different stage 2's.

Did something actually happen to your stock turbo?

Would love to see dyno results for Stage 1 but the guys at protuningfreaks told me gains should be 50-60whp/tq. No clue if that's accurate but the power gain is very noticeable and the car is much more fun to drive aggressively now. |

What’s up guys. I’ve already flashed my car to the stage 1 93 octane. I plan on flashing stage 2 tomorrow after I install my high flow cat as new plugs tonight. Just have a question, what’s the difference in the stage 2 93 octane flash and the stage 2 93 octane (agg) flash? Is it just more aggressive burbles?

Are any of these "less detectable" by a BMW dealer (Mission tuning or Bootmod)?

For a while I assumed it was a mechanical issue. I've done boost leak tests and smoke tests and everything checked out okay. I replaced the boost solenoid and this also made no difference. My next assumption was that my wastegate was failing or is worn. I have a pretty decent wastegate rattle and was going to try adjusting the wastegate actuator (which I've been slacking on doing as I'd have to remove the downpipe to do it correctly) to see if it made a difference. I've also opened a ticket with PTF, tried to explain the issues and had them review my logs. They've told me that everything looks okay. Although if multiple people are having this issue I'm starting to lean towards this being a tune issue? I would think if my wastage was causing this issue the wastegate duty cycle would have been out of wack and would have been caught by PTF reviewing the logs. From what I've seen there is very little development being done on the PWG N55 OTS maps considering the majority of bm3 users are n55/b58/s55 EWG vehicles |

I also installed XHP software and I'm sometimes getting some very harsh issues with the power cut on the fastest upshifts in M mode, but it's not "slingshot" or "lag", it's very jarring, and I'm not sure that it's MHD's problem since every other transmission mode seems to work perfectly.

I think to clarify further, I only feel this weird lag when I am at WOT. It’s actually super smooth when I am accelerating gradually for “normal” driving vs. my “spirited” driving. |

I'm not too experienced with autos but from what I've stumbled across it seems like most tunes manipulate torque limits to fool the tcu and get around the torque limitations per gear. No sure if that could be throwing off the XHP tcu flash? BTW - Cool to see you're in Oakville! Just recently moved in the area and you don't see many modded F10's (or even modded late model BMWs). I've only stumbled across two in the last six months. I see a grey f10 at the go train that looks pretty clean with an aftermarket exhaust and I've driven next to white F10 on Dundas that looked lowered and had an m5 diffuser. Not sure if any of those happen to be you? |

I was evaluating both BM3 and MHD this winter before purchasing in early spring and I was really on the fence. One thing that tipped the scales sligthly was that MHD & XHP (supposedly) partnered together. (One other thing was MHD's linear throttle map option) MHD is flashed in "6MT or XHP" mode where there is no rescaling of reported torque values. XHP is flashed with torque limit of 800Nm in every gear at this point, though if I'm flashing a map update in the near future I may put the "AWD" preset torque limits in just for safety. The way I generally drive, I am not intentionally exceeding the factory torque limits in 3 & 6 anyways with any kind of regularity. I like my equipment to last. Supposedly I have launch control now - I'm probably not even going to test it. My worst XHP M mode upshifts are nowhere near WOT. More like 40% throttle. You'd swear I ran over debris. For all I know something's up with DSC and the car is also applying the brakes. It's not very frequent but still pops a couple of bad shifts per week. They are decidedly not drivetrain friendly. I don't know what's going on but I'm not getting a lot of traction with either MHD or XHP at this point and I don't see reports like mine elsewhere on the internet. ISTA+ shows all modules have no stored codes. Quote:
