F350 Super Duty vs 3500 Denali vs The Ike Pulling 30k lbs

I would like to see a dyno sheet on the new Powerstroke. Maybe my assumption that the engine builds power evenly throughout the power band is way off base. It could be that the torque builds rapidly, then levels off before dropping sharply. If so the power would build much quicker earlier in the power band which would explain why the Ford ran such low rpms and why the Duramax couldn't keep up.
