If I tune on a hot day say 98 with 98% humidity will it affect numbers if I tuned on same dyno at 65 with 20% humidity? If so explain as I don't quite understand.

Most dynos will not effect the numbers. Most have a weather station which takes into account air density and corrects your numbers to read on par with other correction factors. But in a real world situation yes it does affect your power.

Spider unfortunately the weather does change the performance and A/F. I had tuned my rappy near perfect via the sparkplug when the weather was dry and hot (85 or hotter) and when I went out on a 65 degree humid day the plug came out black after the ride. I guess the only remedy would be an auto-tune.

That's odd, the IAT and MAP sensor on the Raptor should account for a change like that. And you would be suprised how a dry 85+ day can be close to a 65 humid day in air density, since the more humid the day the less air you're getting into your intake charge.... Now your bike has me pondering :lol:

So should I have it tuned in Florida at crazy heat and humidity. That or drive a couple hundred miles longer and have it dyno'd closer to home less humid by EHS instead of Walsh race craft.

I can't find a dyno in 400 miles of me,lol I usually dyno in Florida but was thinking North Carolina,because it's more like where most riding done elevation wise and humidity wise. Plus I hear Eric knows his shit.

The weather does play a factor by what Ive seen. Bikes that are rode in the south need a touch more fuel in the tune than say bikes rode out west.
