Not exactly... Your pic has a button to switch PASM (suspension) between normal and sport mode... Another button to turn off/on PSM... And another button to turn sport mode on/off.

As I stated above, sport mode will affect the extent to which PSM is disabled when turning it off at the same time as sport mode is enabled. It does not affect how PASM functions, however when you enable sport mode PASM will also switch into sport mode by default and the PASM button will also light up. If you choose, you could then switch PASM back into normal mode but keep the car in sport mode. Does that clear up any confusion?

Whether sport chrono (sport mode) is important to you depends on how you intend to use the car. PSE maybe isn't as important if you're just going to gundo hack the mufflers, but it would still add a little bit more sound because it opens up a 2nd muffler outlet that is sealed in mufflers without PSE.
