I had a map when it was in the mid 80's and I use it year round. It runs great in the winter and slows down .1-.19 in the summer.

With the PCV, 2 maps can be loaded so if you have one for cooler temps and one for hot days, you could run fairly consistent.

When the DA is high, aka "bad air", you can usually take some fuel out of the PC map. That is assuming that it was mapped in "good air".
On the other hand, if you mapped it in the heat and humidity on an outdoor dyno you can add some fuel when it gets cooler. Often that is the case when it gets very cold outside; you can add fuel. You might try adjusting the map by 2% in either case, and see if your mph improves at the track.
The best way to do mapping is with a data logger.
