The 6.2l's numbers are with premium fuel. You'll see a little asterisk on all of Ford's literature. The EB's is with regular. Put premium in it and guarantee the peak numbers will be close...at sea level. But I don't live at sea level. The 6.2l loses power a lot faster with elevation. I also think a turbo helps in hot weather. You might ask my thinking before jumping to conclusions next time.
Yeah......you’re going to have to post proof about the premium use for the 6.2. Never have I seen that.
Here’s a 2016 brochure.

He is correct. The dyno power numbers he posted were from the F150 6.2L which had higher output numbers and used premium fuel to get there.
Page 6 at the bottom 2014 F150 Brochure
" 5-6.2L horsepower and torque achieved with 93-octane premium
fuel"
The 6.2L in the Superduty only required 87 octane, but had 26 less hp and 29 lb-ft less torque.
Although I never needed to use premium fuel in my F150 Ecoboost even when towing over 9,500 lbs in the Texas heat. The manual said it was recommended if I wanted the best performance(i.e. bump in power) but it was never needed.
