If CEL is not an issue, I would suggest you to go with the latest BMW software. My expericence with Gintani tune shows that there's no difference between two, Vbox verified. I had multiple runs with and without the tune on the same day.
My friend (also 2012 btw) has BPM tune and his car showed the same time, although we did not run it on 241e and I can't really tell if there's difference or not.
My other friend (2013) is running 241e without any CEL delete or whatever, yet he's showing the best times.
Hope this helps
UPD: every car has Akra evo
