ORIGINAL: 12 volt
humidity can actually reduce air density and performace

humid air expands more when its heated from compression, giving you a higher compression ratio.. not much, but enough to notice it running better. water expands bigtime when its heated.
a turbo car you can really tell the difference from a hot 90* day from a foggy cold night.

what i was trying to say is humidity is diffrent form water injection. By having more humidity you are going to have less air in the fuel charge and less fuel (less air denisty). this is why people make CAI so they can have a cooler densor charge.

Somebody was very nice and PM'ed me andcomfirmed my theory:
The IACmotor controls changes in Barometric Pressure (among other things, but I'm just concerned with barometric pressure) in conjunction with the throttle position sensor and the IAT sensor among other sensors..
From what I was toldthe IACcould be the reason for the inconsistant throttle response and extreme changes in power.
