Would definitely appreciate the explanation, and if true is it possible to develop a possible gain of 8 - 10 hp (back to pre ecu tune peak) just by driving it hard? Does not seem intuitive..

Peak hp and torque change daily.
It is definately weather dependant.
In my opinion I believe your dyno results would be identical had the temp on the 2nd dyno been 61-62 degrees.
I would call the dyno shop and have them do SAE corrected #s on both days so you can do a more accurate comparison.
While the new map is loaded it may simply be a matter of teaching the car to run utilizing the new parameter's. And yes you may need to have the ECU redone. Here is an example of why dyno #s are not the entire story.
I went to a dyno day with a buddy, his CLS hit 440, mine hit 408, we lined up outside the shop at a stoplight, light turns green we go full throttle guess what? My car was faster...go figure
