Compared to your previous dyno, temps are 8* cooler, pressure is 1.1 in-hg higher, and humidity is 23% lower. These will make a BIG difference.
Do you have the actual file? You can convert it yourself to SAE or STD with winpep.
I hope you don't think I'm trying to shoot you down or anything, I just don't want you to think your car is making more power when it very well might be making the same as before ( or not, who knows ).
The problem with all of us not using correction factors is that you may dyno 550whp at 20* temps but I'll dyno 500whp at 80* yet both our engines could be just as strong. CF's are there to make the playing field more even.

Ill try to get the files,it was 69 degress out and not really cold like a 20 degree day.
I took it to the 1/4 mile last night and did 4 back to back passes of all trapping 120+ when last week in same weather the car barely broke 115.
look at my a/f it went from 10.0 to 11.8
car def feels faster on the street and I think I even said it feels like 20whp up top end with the but dyno lol.
Im trapping the same as I did with a 180EC pulley on 109 race gas with a evotech 178 that really a 175 if you measure it in the groves and regular pump gas.
car is no doubt making more power up top end
heres a pic I snapped with my cell,you can see my track numbers still on the car from last night.I froze my *** off waiting for dima to show up and he got pulled over doing 186mph in his e55 and had 10 cop cars pull his car apart with search dogs

I was pissed 2-3 weeks ago when I had a car trapping good and then do more mods and only lose 5 mph in traps and see 470whp sae and 482 std with a 1.03 cf and tring to figure out what the heck happened to get my car running so rich up top end.
The funny part is the car is on the same exact file for over a year now and its adapted to bigger pulley,bigger tb,made more power,lost a heck of alot of power and then made more power and higher traps with not changing the tune at all.
If anything I want to add fuel from 2k-4k as the car is running a little lean for my liking.
Its setup perfect for a 172mm pulley right now
