Anyone have experience with DME tuning on their m550i?

Found the DME website and they're advertising a very reasonable "stage 2" package that includes tuning for vehicles with downpipes and ECU unlock that results in 700 HP.

Anyone used DME and have any feedback? This seems like one of those "too good to be true" situations, especially for the price. See link below.

shipping everything to Europe scares me

Shipping to Europe is only required for 2021+ cars. But it looks like DME still requires your ECU to be mailed in, and it's not clear if you would need to mail it in again for any subsequent changes. It's much easier and cheaper to flash it in your own garage with M-Link and BM3. Unfortunately we don't have good dyno numbers to compare the tunes against one another so it's impossible to say which is best.

Dang I wish someone had some good dyno numbers for BM3 on a 2020 up N63B44T3.
