How can I tell if my N63TU is tuned?

Hello,

I sold my 2012 650i about a year ago in the hope that I can get a 650i with an N63TU but the prices went through the roof. I ended up buying a 2014 550i with an N63TU. In sport+ mode, 550i feels faster than 650i. I know it has an additional horse power but either I don't remember how fast 650i was or 50HP makes more difference than I imagined or maybe this car is tuned. In any case, I am wondering how I can find out if my 550 has a stage 1 tune (Weistec or something else) without taking it to dyno? I do have ISTA/P as well as ISTA/D.

Thanks
