Problem about n47s 123d

[GabrielloN47S]

Hello guys, I also have a series 1 123d bought about 3 months ago, the car does not have egr, DPF and flaps being off, absolutely all good and beautiful, the car goes super ok, pulls super well, it has cancellation software, not with black smoke, only very little in good load and now I come back to the problem:
When it's hot outside, i.e. over 25 degrees Celsius, the car doesn't want to pull at all, that is, at 4000 RPM the car stops pulling and I have to start it again to go correctly and so always when it exceeds 4000 RPM in the car, I changed about 2 vaccums, I checked certain things, if you have ideas and opinions, they are all good to take, thank you!

Stops firing : the turbines enter a protection something stops driving and goes without both turbines, turn it on comes back perfectly
