Sounds accurate.. I can hear my valves open as I press the gas pedal in sport + when my car is warmed up. Efficient doesn't seem to open the valves as well.

I've reconnected one of the valves with the OEM bmw harness, ditching the VS2 harness
My exhaust behaviour on start up is:
- On efficient, valve stays closed, press the accelerator in neutral, valve stays closed
- On Sport Plus, valve stays closed, press the accelerator in neutral, valve opens (so opens but not on start up)
Can anyone confirm this?
