2020 Ford 7.3L Ike Gauntlet

I'll somewhat agree with you but I'd think that it was a combination of both the 7.3 and the 10 speed. I have a 6.2 and I think a 10 speed would improve it but not to the extent of pulling the Ike in that amount of time.

If this engine gets 6.2 fuel mileage or more it should be a winner.
