Question What does BMW know that the tuners does not?

Hi

Car: F20, N55, PWG, Pure Stage2

So...after 30 revisions from both a custom tune and the BETA-OTS I still dont have a car that is running right with the Pure Stage2 hvis is frustrating me quite a lot to be honest

So, I was very surprised when I logged Stage0 and saw how well it controls the turbo. How the $#%@ is that possible? What secret sauce does BMW have in their tune that all the brightest MHD tuners has not discovered yet? I am sure the tuners are trying hard, but 30 revisions...

I have asked this question many times before and will try again: Has anyone had a big turbo PWG tuned sucesfully? If so please shoot me a PM, thanks.
