Yesterday morning on a clear, quiet drive to work I noticed something spectacular about how my fr-s was feeling. Everything about the engine and throttle response was crisp, accurate, and buttery smooth. As my drive went on I put more and more focus on the rpms and just how quickly the needle punched through each mark on the tachometer.

It was a little after 6 am when I hit the road and the air was so clean, cool and completely still. I live on the coastal region in Virginia and generally we have a pretty fair amount of humidity... on a hot mid-summer morning you can seemingly break a sweat before the sun even peeks. Being so caught off guard by the increase in performance on the pants dyno, I reminded myself to compare the ride home around 4pm with plenty of hot air and a more humid atmosphere. Sure enough things started to bog down a bit. The throttle response was not as sharp and there were definitely moments where the revs seemed to choke(not talking about torque dip). It just felt like the 86 had run a 5k and was gasping for air, compared to in the morning where it was free to be out of its own way.

In an attempt to conclude the weather as the factor, I did check the temps on the google weather app, and oddly the humidity reported contrarily at 89% humidity and 64 degrees in the morning; and only 76% humidity and 71 degrees during the ride home, even though there was a brief shower and noticeable moisture slightly before that drive. But I have no how accurate or real-time the data is for the app.

So have any members experienced this same behavior in humid climates? And are there any tricks or minor mods to help circumvent the engines response to hot air and make it more adaptive?
