I'm able to find this for the 6 cylinder motors, but this information doesn't seem to be out there for the N63 on BM3. I am just wondering what tuners seem to be the most knowledgeable on BM3 with this platform, also what people are charging (it's disappointing BM3 doesn't list this).

Mike at X-PH sells the Jordan tuned flash, and I’ve seen them range from $300-900 from other companies. That being said, most include multiple tunes with data logging, so there is some labor involved. I contacted bm3 about the weak power my ots tune makes and they wanted data logs to see it. Between the price of the software and a custom tune, I’m likely going to just sell the bm3 and order the active autowerks flash from X-PH if their customer service can’t resolve it.

FenixMike Any update? I recently purchased a 2016 550i and researching tunes...was thinking BM3 was the way to go, but now not so sure.

I sent in the data logs today. Oddly enough just to rule out everything, I flashed back to factory, then reinstalled the ots tune and it definitely has more power, and shifts harder. When I originally installed it, I did get an error, then tried again and got a pass, but I’m wondering if a sector of the pcm didn’t get written properly. My cold start was off and no codes for catless, but no power gain. This time I definitely have a stronger top end and better shifts. Datalogs reported 13 psi that tapered off to 10-11 towards redline, so we will see what the techs say. Not really a track around here to see what it runs, and no dyno, so if they bless it, going to have to figure it’s doing as designed.

Sadly I drive a gov vehicle Monday - Friday and rarely go more than 5-10 miles in my bmw on the weekend, but I am going to Phoenix next weekend so I will have some abilities to play with it.

Thanks for the update. I had MHD flash tune on my '15 335i and was happy with that, but they don't have a N63TU tune and don't have plans to do one.

Anyone know how long the BM3 N63TU tune has been available? In other words, are they still working thru bugs?
