It would be interesting to know where that blue chart above came from. Is it a Raptor truck? Are they running high octane fuel?
The Raptor at the time the 6.2L was available, only had the 6.2L. The H.O. 3.5L didn't come out until after the 6.2L was dropped. The regular output EcoBoost probably won't show a meaningful difference on a dyno. The 91 octane recommendation helps mostly with fuel consumption when towing, and can reduce throttle lag from timing adjustments, but that doesn't happen unless the engine is already very hot. The high-output 3.5L would benefit, but it makes ~500 ft-lbs. of twist.
