I don't trust comic font in 24 size.
Looked into the scripts.
each script is conterparting each other. The most weird one is UNLIMITEDBOOST_2 that is a copy-paste massacre of multiple other scripts into one... I don't like to invest time into proof that for you. But if you can read a little bash and if you can see how much things are commented out and the many settings get repeated but change values... it makes absolutely no sense.
The sadest part is, that it seems that every reboot you make... everytime your dalvik cache gets cleaned up. this slows down your phones startup as well as everytime you will start an app the cache has to be filled again... huh?
maybe some few tweaks do really change something but most parts are crap.
many scripts are copies from 2011. In that year no ICS or fresh new xperia phones have existed so these values that will get set are not optimized for us and not well tested an I guess it's only "lucky numbers"
I can't see if this really tweaks your phones positively but in one case I am sure: It won't boost it. It possibly just speeds it up in a way you just will see under lab circumstances.
Decide if you trust comic font or the content inside that zip...
