For example, when I have my car dyno tuned friday it will be about 80 degrees, very low humidity, pretty close to sea level. Are these decent conditions?

Yes, those are going to be pretty good conditions. If it is very hot with high humidity, you are going to see some negative results but I don't think that it would be that big of a deal. Besides, hot and humid is the weather that you may be driving alot in during the summer.

If the dyno numbers are SAE corrected, then they will be close. The correction factor isnt perfect, but helps. The problem may be is if you get KR due to the intake air being too hot and if the motor is heat soaked.

the dyno program is just a linear program based on temperatures up to about 90 degrees. it doesnt compensate for humidity which kills hp.

I don't know if that is true. When I had my car dynoed the first time it was hot and humid and it made the same power three months later when it was cool. THe dyno guy told me it takes three external factors into consideration. He had three large gages sitting on the wall. One measured humidity, one measured temp and the other measured bar pressure(?). It may of been for show but he seems like a stand up guy. It was also a two year old Dyno Jet. Who knows.

FWIW, it's 5:35pm 93 degrees, relative humidity 13%
