Sony E. C902 Volume tweak needed

Is there Volume and Mic tweak I can use to increase the volume up on my C902, [ I understand the normal vol up and down buttons], there is times when I'm out and about and near traffic I just need a slight increase more to the ear piece volume[ I'm not talking RAMPING it up to break the earpiece] and I dont want to use speaker or a earphones..

On a Motorola Razor there was a Hex-Dec Program you could increase the Vol and Mic settings and write the audio driver back to the Phone, which was great and easy to use,

Does Sony have anything like this ? where you could alter some driver settings ? and use A2uploader to place it back on the phone..
