Default Power curves for F150 and F250 6.2L engines

Thought some may be interested in seeing how the F250 6.2L torque curve compares to the F150 6.2L.

F250 6.2L Power Curve:

Neither of those look like actual dyno graphs. The bottom one looks like an excel spreadsheet.

I would love to have the 6.2 but that dang ego boost looks really good on paper.

These are the actual Ford Flywheel dyno results charted. They are not wheel driven dynos that can have results all over the place.

I took these pictures myself right out of the marketing hard book at the F150 stand of the dealership. The F250 dyno results were copied right out of the 2012 superduty brochure.

Where did you get your data. You results don't line up with Ford's flywheel dyno results and they don't line of with either of Pickuptrucks.com rear wheel dyno charts that even ford engineering was a part of. Your chart makes the Eboboost curve look much better than it really is while making the 5.0L and 6.2L curves look much worse than they really are.

@Jonbar

I know that the Ecoboost makes more power than the 6.2L before 4,500 rpms, but those charts look off especially the HP one where the 6.2L should be above 400hp.

I assumed that's where those were from. The excel crack was just a sarcastic comment. Either way, I'm skeptical of those curves/numbers.
