Any thoughts on whether the humid air is effecting my performance? Or am I just imagining things?
If it is really that kinda humid up there then-yes- it could be affecting your performance.
As humidity increases, the density of the oxygen in a given volume of air decreases because the water (humidity) takes up space. This in turn means you have less combustibles in a given air charge for your engine.
Hotter air also decreases performance because in a given volume of air the molecules are farther apart, also resulting in less to burn in a given volume.
I loved the winter in New England when I had my supercharged Dakota- The butt dyno went WILD..and I real dyno'd about 2-4 hp higher while tuning. Jet engines are FAR more sensitive to these phenomena.
