Since this ends up covered in EVERY dyno thread It may be easier to move all the talk into one thread so not to mess up the conversations others are having with the talk of over/under rating.
We know that not all dynos are equal.
We know that weather and DA effect numbers.
We know if a dogs farts in the wind in Nebraska can effect numbers in Florida.
That said. Based on my own observations of all the dynos I have found here and YouTube so far THIS is what I PERSONALLY find the most likely case in expaaining the 2018's numbers.
No one has posted a reliable number hinting that the engine is making over 470 without taking into account the older weather/sea level, ect.
The cars are NOT under rated, they are just Under advertised, and Ford is trying to keep engines in the upper end of their SAE rating allowance.
All dynos have been mostly in the 413.5-423.5whp range which is in line with the 10-12% loss estimate for manual and auto. Some people have been a bit higher, but also in 30-40* weather.
If you have some counter oints, or find a flaw in my math please feel free to point it out, but as I said, looking around this is what I feel is most likley going on.

- SAE allows 1% variance.
- 465-1% is 460 (the advertised number Ford chose, if Ford is not allowed to advertise the lower end of the SAE ratings please let me know)
- 465+1% is 470 (closer to what most people are getting when you factor in the proper drivetrain loss of 10-12%)
