First time post on RL from a pretty new 2017 C2S owner. I've done lots of searching and it's still not getting through to my thick skull. My PSE appears to be backwards. When I activate it, the tone goes from a deeper tone to a more muted tone. I've attached a video of the valves in action from startup. It starts up in "normal" mode and at the 0:30 mark, I switch it to "sport" mode. Does the valve operation correlate with what it is supposed to be doing? Is it possible that the vacuum lines are switched at the COV causing this? I know there's only one vacuum line to the exhaust valve itself, so based on my limited understanding, the next culprit would be the COV, namely how the tubes are connected. Thoughts?
