I processed the video and increased the audio, so as to hear the sound. So in it is not that loud. But inside the vehicle you can definitely hear it. It was not as loud before, it it as only doing it at Level 2, at the end of the run. Now I can hear also the air flowing and I guess the valve is lauder.
It would be nice if you can record it and compare.
