[IL X5 M60i]

I've gone the tried and true fuse pull method with many BMWs (M550 being the last). The M60i has flaps on both sides, as confirmed by a $25 screen endoscope purchased off of Amazon.

At what RPM level do BOTH flaps open? On previous BMWs, it was put in sport plus after oil temps were warm, beat on it and pull the fuse.

I have searched the forum on this topic. Lots of people who have gone the controller route for the flaps. I don't see that as necessary as I have had zero issues in almost 8 years on multiple BMWs with pulling the fuse.
