Thats the exhaust burble, totally normal.

Just preparing myself. Planning to take it slow.

6 should be fine any longer and you might have issues maneuvering it

The burble part I can control with BM3….but what you can hear here I don’t think is the burble. It only happens at higher engine speed speed and u let go of the gas rather abruptly. I describe it as putting your tongue on the top of your mouth and vibrating it ….that brrrrrrrrrrrt noise.

That's exact the conditions required for the over run conditions to occur and cause an exhaust burble.

Unless you went to the custom tab in bm3 and turned off the burbles all the way, it will occur. Even the stock tune has burbles.
