PC 2 maps and air quality

[OB_busTa Kaw]

Say you get a map that works on the dyno. The air properties could be totally different on different days...will the fuel injection compensate for the minor differences or might you need a different map for different days to make the best hp.
I know no one would set the maps everyday but I was just curious...this is the first time I have had to deal with fuel injections

I prefer not to go into detail but it is several:
Atmospheric pressure,coolant temp, Air intake temp.air intake pressure sensor.
