bootmod3 Exhaust Flap Control Demo

[proTUNING Freaks]

Thought we'd share this vid an N55 customer sent in this morning of bootmod3 app's electronic exhaust valve control. In this case its running on his 2013 335i.

This functionality works across all F series cars with electronic exhaust flaps. Listen to that flap open and close, don't put your finger in there!

Thanks Dejan!
