Background - Assume you are parked. When you hit the PSE button the exhaust flaps open the car sounds louder, fun. Then you take off and from approx 2000 to 3800 rpm the exhaust valves close again as this is both the common cruising rpm as well as the range that the flat 6 produce the most drone. Then as you accelerate past 3800 rpm the valves open again.

The PSE mod makes it so if you enable the PSE via either the button on the console or the mode on the steering wheel it stays open even during that 2000 to 3800 rpm range. This is where you will notice the drone that is now apparent with aftermarket OAPs.

It is nice to have the option but for me I prefer the factory programing after installing OAPs.

Okay that I knew. I think some valve controllers can do full open, full close or stock PSE like you mention so all three options.

Indeed, including our very own DIY version found here. It does everything the fancy ones will do, and costs less than a tank of gas. Just say'n.

It doesn't do everything the "fancy" ones do. Can it change redline? Add free rev in neutral? Remove auto start/stop in normal mode?
