I would lose alot of HP here in phoenix between summer and winter, .5 and 3-4mph. If you can find someone at the track with a portable weather station, ask them what the corrected altitude is, then use this to adjust to sea level

Alot of times, hot and humid are the same as running at 5000+ ft altitude..
