Non M SMG/ SSG diff ratio change?

Was hoping someone here has successfully changed diff gear ratios on a non m smg/ssg 6 speed.

My thoughts at the moment are leaning towards the possibility of changing the transmission module from a Z4, or if it is possible to load the Z4 program onto my 330 transmission module, which would possibly give me the option of either a 3.07 or 3.48 final drive.

Any advice/ experience, other than getting rid of the ssg, would be much appreciated
