I found the problem and solve it
The problem for this noise was the air K&N filter.I clean it using K&N kit and now this noise dissapeared.I was also in BMW service and they told my that is possible to be turbos responsible for this noise...
Now everything is back to normal

The engine is mapped to 360hp.I found this video on youtube that looks like my sound problem,but now,after I clean my KN air filter,the noise is gone.
