undervolt and overclock performance and save battery

You can save battery and have great performance by undervolting/overclocking cpu and underclocking gpu, the best way i found is a script in rom toolbox.
i run on maverick 4.5 and try this day on 4.0
and this link :

http://rootzwiki.com/topic/14511-opptimizer-projekt-milestone-overclock-for-omap4-devices/

for me my values are:
for cpu
mpu_opps[3] rate=1200000000 opp_id=3 vsel=61 u_volt=1345000
mpu_opps[2] rate=800000000 opp_id=2 vsel=55 u_volt=1200000
mpu_opps[1] rate=600000000 opp_id=1 vsel=43 u_volt=1100000
mpu_opps[0] rate=300000000 opp_id=0 vsel=26 u_volt=1005000

for gpu
gpu_opps[1] rate=307200000 opp_id=1 u_volt=1125000

I started all the values with romtoolbox and create a script at boot
open rom toolbox / open tools / open scripter / then create new script

script name:
overclock
commands:
#su
echo 3 1200000000 1345000 > /proc/overclock/mpu_opps

save, and click on your new script and select "at boot"

re create a new script for the other values, for me a total of 5 script, 4 for the cpu and one for the gpu

The governor is mot_hotplug or boostedassV2.
I tried a lot of voltage values, the more stable are here for me.
I think this run on many rom, not only on maverick
The dev can implement this in rom ?

Can you export your scripts and upload it here?

I just create a line in rom toolbox, not a zip or flashable script
