Getting closer
By increasing the volume of air thru the evaporator you have introduced more heat into the refrigerant 62 Deg vs 57 Deg. ergo more efficiency. The result is less power 0.479Kwh vs 0.575 Kwh.
IMHO larger compressor Big NO
The existing larger evaporator YES
Moving more air thru the evaporator BIG Yes (fan shroud. bigger fan, 2 fans)
(How much more free heat can you get into the refrigerant.??)
(beware of diminishing returns)
Calculate the BTUs see how your stacking up.
