I did not mean to sound contradictory there.
But rather giving my opinion,
    I see the firmware kind of like the differential in an automobile,  and the software as the transmission.
It is a mechanical job to change the ratio in the differential,  very seldom done on most consumer vehicles.
while your transmission may change gear ratios hundreds of times, even in a short trip.
  While you can sometimes get the results you want by say changing the differential gears to run a better time at the dragstrip,
 But,  the car then becomes unpractical to drive on the highway or to work everyday.
Changing the firmware 'may' change how your hardware interacts with your software.  OF Course this is not always a bad thing,
But something to consider,  
   as you may end up needing to re-tune your software after changing the firmware.
IF this is your 'cup of tea'  go for it.
