What would make more of an impact on the modified results...temp or humidity? I am assuming colder temps have the potential to provide higher power output due to more compaction of air, however, what effect does higher humidity impart?
With these differences in test conditions, if all conditions were the same, is the increase in hp/torgue justified or would it be more or less?

The specific air volume in test 1 is 0.840 m^3/kg and in test 2 0.866 m^3/kg, so the expected power output in test 2 is 3% higher than in test 1. Overall this means that about 2bhp was lost by adding the intake, or more likely no difference if a reasonable margin of error is applied. Calculator here:
