Default [Q] what gb kernal do i use to disable perflock?

im on the latest gb ota ruu. i rooted and flashed the 2.11.1111 junobear hboot. i went back to stoke because ics battery sucks and i use my phone at work for music all day. the phones dies. so i tried to disable perftlock cause i found thats whats eating up my battery. ics is all glitchy, so back on gb and i still cant disable perflock on the stock kernal which i thought i could. any ideas?
