We could all tell though that each of our cars were pulling significantly harder than before. However, the difference in the temps and humidity though was from 84 degrees and 30% humidity on the first dyno day to Saturday's 104 degrees with about 74% humidity.

Interesting to see how much difference the temps and humidity make for power output. I drove the car later at night when it was about 85 degrees and less humid and it was a whole different animal. Dai and James noticed the same thing to a large extent.
