You don't need the flasher to OC using Titans kernel.

Can I suggest that you read through the wiki on over clocking before you actually do anything, everything is explained in there.

If you have kernel for power users and kernel for power users settings installed and your phone has been rebooted, you can do the following in the terminal (provided you have rootsh installed) :
You have now successfully overclocked your phone.

To make it permanent
You can change the min/maximum frequencies by doing the following:
Where 250 is the minimum frequency and 1000 is the maximum frequency.

To save this new config:
Where myconfig is the name or path of the configuration file to be created

You can then make this the default by using the code above.

Have fun.

You might want to look at 'Transition Control' in the repos, it makes such a difference to the speed of the UI.
