Jeff......
Our temps that night were 35C and i was drenched totally......i guess it was humid..... and i used 20% nitro cool power only.
But I think you might be right coz the last time i ran that car it was at the parkin lot and i tuned it @ morning around 7am........
I am going this thursday again so might get to work on tuning it again for the night.
