So with the uncorrected numbers what does that mean?

Uncorrected numbers are the ones that your car produced under the hot conditions that you dynoed at. If you have the dyno run files and the winpep software and look at your VZR numbers uncorrected, more than likely, your numbers will be LOWER than when they are corrected.
Done properly, corrected numbers allow us to compare two dyno runs done under different weather conditions.
Your two runs are corrected using the STD correction factor. STD corrects to 29.92" of mecury and 60*F. This means that your VZR run @ 100*F will end up with MORE power if the numbers are corrected to 60*F. Your other run is also corrected to 60*F, but since the temps were in the 70*F when that run was made, you do not gain as much hp when you correct as in the more recent run.
My advice is to download the winpep software for free from dynojet and have Alfred e-mail you your run files and play around with the dyno runs and the correction factors.

Corrections or not, if it was too hot in there, his car could have heatsoaked quickly from insufficient cooling and possibly started knocking or pulling timing like a ****. Now I saw that with my own eyes. A car made power to 7krpm and would have kept going up until that badboy fell flat on its face from heat. If its too hot, it can affect topend. No data logging was going on at the time of Mr. Birdie's run so I guess, we'll never know. Take that beast to the track.

This happens a lot in these forums. People complain about the heat impacting the power output of their cars while posting CORRECTED numbers. You should not do that.

Blah, I'll just redyno the car at similar or cooler condition. This would give me a better understanding, all I know is at night or when its reach in the 80's. The car pull hard mid to top of the power band.

IMO, the best way to compare dyno numbers is to run the car on the dyno for a baseline, do the modifications while the car is strapped to the dyno and run it again with the least amount of time between the runs. This way you can run UNCORRECTED numbers. But this is problematic if you are doing time consuming modifications.
What you posted here is the proper way to do it. My issue is with saying that heat was a factor in the numbers produced by your car when the dyno sheet is corrected.
I would love to see an uncorrected dyno sheet for your car with 100*F.
