I was actually curious about the V6 SuperCharger too because I had not messed with it. It came out a bit before I switched to my Sprint HTC EVO 3D, so that is probably why I did not notice it, though it could technically benefit any Android device.
Anyway, from my understanding of it after reading up on it, it basically adjusts the threshold for killing apps based on the minimum free amount of RAM for six different states of said apps or processes. So basically, it controls how Android manages RAM when it starts to get low. So, the lower you set the threshold for a certain type of app or process, the more likely it is to stay in memory thus not needing to be loaded again and slowing things down. By the same token, higher thresholds will force certain types of apps or processes to be killed and removed from memory sooner, thus leaving you with more RAM to play with. Now, you have to understand in Android, the more RAM used, the better because unused RAM is a waste. Additionally, in Android, even what looks like unused RAM is actually being used to cache system processes to speed things up behind the scenes. You might say, but is this not like a task killer or manager? Technically, no, because it is a modification of parameters used by the task management built into Android, which is still letting Android be more efficient at killing apps and processes than an external task killer ever would be able to.
