Hmmmm, I could have swore I read something not to long ago about the 6.4 being a single turbo. My bad then I guess. It still makes the same exact power as the single turbo Cummins. Less turbo lag but I bet the Cummins will win in a race, New 6spd Aisin trans with 4.10 gears
Like I said twin turbos, when are you going to learn...............if I type it or say it, then it is a fact.
The 6.7 is also a proven engine. Cummins engines are tested in heavy machinery for something like at least 5 years before there ever put into a pick up. They do that so theres no "6.0" kinda situations
The 6.7 Cummins is brand new, it has not been used in any other applications "for 5 years".
