Hi 1JB, I have just a few comments for you.
I have the Sport Chrono and like it! This was one of those options that I just did not know if I really wanted to include in my custom build & factory order. Many people said it was a "must have" while others said it was "as waste". Just about everyone said the "wart" on the dash looks awful and to some extent I agree with the wart comment
. Ultimately I decided to get it, because I did not want to have the "buyer’s remorse" thing and in principle the SC makes sense on paper from a technical perspective. And for the $920 I was willing to roll-the-dice!
I drove several demos, with and without, but I could not really tell the difference. I think this is because I am not really familiar with the car and not really getting into it from a performance standpoint.
In your post I think you are confusing PSM with PASM (or it was just a typo!
).
PSM- is Porsche Stability Management (standard on the 987)
PASM- is Porsche Active Suspension Management (option code #475 for $1,990)
Sport Chrono interacts with both. AND THIS WAS THE MAIN SELLING POINT TO ME. While I do not have the PASM option I can definitely see the added advantage of SC with the standard PSM. With SC engaged, you can give more driver input to the car, especially in aggressive cornering, before the PSM kicks-in to make adjustments for under steer & over steer and power to the rear-end. As I see it, this is the major benefit of SC and makes it more worthwhile vs. worthless.
As for making the car have more throttle response...it does...but this effect is less noticeable than the interaction with PSM, for me at least. The car has great throttle response on its own!
SC does interact with PASM (if you have this option) by putting the car in sport mode for the suspension.
SC also interacts with the cars "rev-limiter" but I have not experienced this, since I don't get that high in the rev range.
