They had to build a 8.3 liter just to fight a 6.7 which is absolutely comical

It was confirmed they’re not getting rid of the L5 P6.6 they are making the 8.3 mongoose the upgraded optional motor so now there will be the 66 Duramax the 66 gas and the 8.3

these trucks have enough HP and torque why not improve fuel mileage while towing. I have an old 5.9 cummins and it pulls things just fine I can't even imagine needing 600hp or 1500 lbs of torque
