Shifting through the gears is instant power response 0 lag at all. Top peak boost I saw in 70F ambient and about 35C IAT was 1.2X bar. Which is just over 17-18psi..

Yes, I confirm no lag between shifts and more responsiveness. I just checked the peak boost and the top now is 4-5 psi more than before.
I'm using always Bimmerlink and the Vgate OBD dongle to monitoring the car's values.
Thank you cookiesowns, because I decided to do this firmware upgrade after reading your first post at the end of July.

I just took the car to the dealer and I asked to them to download the latest software/firmware version available for my car (beginning of September).
They said to me ok but they couldn't do under warranty so I had to pay for 2hours labor.
Unfortunately they were not able to say which firmware number version they downloaded...
I just can say, in my case/on my car, it worth a lot.
