Ive contacted turner motor sports to inquire about jb4 and the like and they don't have much advise other than they dyno it, write the flash tune and other than a colder spark plug and charge pipes they really didnt give me much else. I had to point out that i had a x6 not a x3 which at that point the emails stopped!lmfao so i feel your pain. They said a high flow catted down pipe works best, good luck finding one, super sprint makes one.........for 2200+

I have 2011 x6 35i
My car is stock (stock charge pipe/downpipe etc..) and Im using MHD Stage 2 for about 2 weeks already,
at first I had engine fault, (valvetronic codes) but it went away on its own after a few restarts.
so far still driving it
power is really noticeable quite happy with it.
bad side is significant fuel increase even under NORMAL city driving.
Regarding the downpipe, VRSF has catless downpipe. But i still have no plans of purchasing it.
by the way
take note if you have 2012 year model and above:

- 2010-2013 135i N55, 335i/x N55
- 2010-2013 X5 35i N55

I'm not sure what DME bench flash unlock means.
