I agree, the downside to the Cummins is the VERY narrow powerband. Yes, it makes more torque down low, but it's out of breath by 2200 RPM or so. The PowerStroke drives more like a gasser, which is what most people want. The Cummins ISB drives like a large truck motor. To get good fuel mileage at highway speeds, it really needs even more gears than it already has. (5-auto, 6-manual)
