RAM 6.4 Ike Gauntlet

So the old less powerful on paper chevy 6.0 won... by 3 min.. Like the GM, the computer is tuned from the factory a certain way that really doesn't show the true engines capabilities. I still say when you know how to manually shift the gas engine and keep it in the power band, your results are much better. Regardless any gas 3/4 ton made today is a great towing vehicle in my opinion.
