The butt-dyno can be pretty deceiving... I have noticed this myself though at times.
Over the past couple winters in chicagoland being VERY cold besides this past winter I definitely noticed a difference. The car will add extra fuel due to the colder air being inhaled to keep things cooler in the combustion chamber, I noticed abysmal gas mileage in 2013 and 2014 winters.
Once the warmer weather rolls in the computer adjusts accordingly for fuel/air and might feel like it is making a touch more power. This is just my understanding of it.

I feel a power and economy gain at about 72 F (standard day temp) and humid; not sure about what % of humidity.

One of my vehicles is a 94 Geo Tracker. Is more noticeable with its puny engine.

Should be slower as the ECU pulls timing when the intake air and coolant temp rise. And trust me, you can definitely feel the difference in Australia :-)
