i didn't say you need titan kernal ! i'm using kernal power 46 and its working just as stock kernal + ability to OC
If you don't want overclock or don't want to flash kernel-power, I don't know if the script is working, because it needs iproute and iptables. You can try it with your kernel, in rootshell type apt-get install iproute iptables. Also I don't think this script is for newbees and I think it is better to install it with kernel-power. At least it is private collection of my phone and it makes it superfast - I'm not sure if I want to share this all!
