Well, to install Kernel Power doesn't always mean to overclock the phone. If you suggest people to read the docs on overclocking, I assume you know that with Titan Kernel Power you can lower the voltage while raising the CPU clock safely, which mean some power scheme might be better than the other.

If you follow the guides there and read this thread, you will find something to change your mind there.

Many have reported battery improvement while using Titan Kernel thanks to the ability of loading your desired power schemes. It is nothing nearly similar to changing your shoe size there.

I myself am among those who want Titan Kernel just to be able to lengthen the battery life a bit without slowing the phone. But sadly, I have to give it up because I always have call quality problems with the enhanced kernel. I am still looking for the "best overclocking app" not to overclock but to find "the best shoe size(!?)"
