How to know if N55 has diverter valve
I recently got my 2018 OG M2, installed CTS turbo intake and when I let of I get a stutu more than a surge noise. Does this mean I have a diverter valve?
How could I verify if its installed or not Thanks |

The turbo flutter is the airflow that passes through the cold side turbine after you let off.
Yes you do have a diverted valve. It’s located on the turbo itself I believe. It’s a black circular object. |

Stock DV makes sound too, It's easy to identify turbosmart from outside of engine bay since it's a one piece, different shape than stock DV. I think GFB has white letters logo on the side of it to identify too.
