I totally agree with you.
The feedback I have had about the always closed option is that users wanted it to quiet the car down when initially starting the car or when high speed highway cruising. And, for those who track the car, to gain acceptance by the noise sheriffs at the local track. Some people also wanted to make sure the car was quiet when they were driving slowly in their residential neighborhoods ... some people told me they were getting complaints from neighbors, especially if they had put on headers or less restrictive cats.
In my opinion, and I have done a lot of research on this, there is absolutely no detrimental consequence of using the Always Closed option.
Love to learn what your results are. I expect after the mods you have made this topic is of considerable interest to you as well.
Best regards,
Steve

There are many owners that have headers and different performance modifications that don't want to sound like a racecar. Maybe when they WOT, they don't want it to sound like a Nascar race just started. I think it would be cool to test it out to see what it's like to have the valves closed all the time. I believe the best performing setting will be the factory setting since it allows for optimum low end torque as well as high end horsepower, but I'm interested to see how the other settings turn out.
