Is -15.2 Long Term Fuel Trim Normal?

Is this normal at idle for my mods. All my long term fuel trims are in the minus category but it is particularly low at idle. Should I increase my injector constant from 32 to 34 or so?

Are the LTFT split or are they both close to -15.2%

The long term fuel trim 2 is -15.7 and the long term fuel trim 1 is -12.3. My short term trim 2 is -10 and my short term trim 1 is -6.
