Lithium Battery owners using HP Tuners chime in

Just picked one up and am using HP Tuners for vehicle tuning (who doesn't honestly?!). For those running a lithium battery, I'm sure you are well aware the nominal resting voltage is 13.3 volts which is higher than the usual 12.6 nominal voltage of standard lead acid technology. For those running HP Tuners, if your diag system voltage low (located under the "system" tab) is set to 12.5 to give the fuel pump more of a boost have you made adjustments to that in order to match the lithium battery's nominal voltage?

Seems like it would be better to match the new battery's voltage and set it to 13.2 volts instead of a standard battery's voltage in order to better preserve the battery itself. I know all I would need to do is change that parameter value and it's an easy thing to do but for sake of conversation I think it warrants the question anyway.
