Hi,

Can anyone comment on how the PSE operates exactly?

Do the valves open and close based on engine torque demand (Throttle position & RPM) or is it merely based on RPM?

Does the car always start on loud/valves open during a cold start?

I heard that if you are driving it comes off/closed at 30mph and comes back on at 50mph - because of some noise regulations or emissions.

How does it behave on the motorway? Can I cruise at 80mph or 3500 RPM with the valves closed if I have small throttle input? That would be my ideal scenario, I don't want the car on loud when I am doing long roadtrips at 80MPH.

Thanks.

If you direct wire the solenoid, you skip all the restrictions and have an off/on switch at will.
have done it in my 06S and my 09S…..love it!
