No one has done a dyno with just different octanes with a Raptor on here.
The PCM does a good job with timing when using different octanes, having said that, most of us do feel the difference.
HP numbers were always slightly higher when using 93 octane.

Ford published the numbers in the owners manual, 401=87 and 411=91+ and you say no one dynoed. Did ford just pull these numbers out of their ass?

Those are engine bench numbers, I am talking about truck sitting on a dyno with different octane.
So your comment was unnecessary.
But I did forget about that in the manual I read 14 years ago, thanks for sharing.
