Hi all,
I recently installed the GFB DV+ onto my 2014 BMW 328i (n20) and have been finding that it is not "fluttering" like it does in all the review/install videos. As well as this when I finished installing it I was left with a bunch of fault codes(that have been cleared) which none of the install videos said would have. Just wondering if anyone else that has installed this had the same issue if not a solution for me.

I've already upgraded my air intake to the mst performance cold air intake (like the videos) and not getting the same effect but when the air intake and turbo inlet is off I am getting the "fluttering" noise.

Thanks
