While these numbers look pretty accurate, I'll call out that the Hemi makes that torque @ 4,000 rpm, where as the Cummins makes it's torque @ 1,700 rpm. Obviously, torque curves being different and all that, you'd need to find apples to apples dyno sheets or manufacture provided data, the Cummins is still going to make a noticeable amount of additional torque, if it didn't then there would be no real need for it right?A short note on torque and diesel versus gas engines - when I selected my gas engine one of the calculations I used to compare the engines used published engine torque x 1st gear x axle ratio which equaled a value I called calculated torque. Now this did not include the transfer case since the high and low range numbers were identical, and this also considered the trucks were running identical sized tires.
Of course the diesel has a much broader torque curve compared to the gas but this is just a snapshot of some real values that paint a slightly different picture. If only considering engine torque we can say the diesel produces 88% more torque but if we include gearing then the diesel powertrain is only producing an additional 17% torque.

Whether that matters to each person or it's worth the price of admission is another question, but it does have the clear apper hand in a way that your chart alone doesn't account for.
This is 110% incorrect. Many Ram HD owners, most in fact, install 37s without any aftermarket bumper. Guys put them on stock Cummins and Power Wagon trucks, so I've got no clue why they would tell you this, it's just flat out wrong.In order to fit 37'' tires, the AEV bumper is necessary.
I commented on this on the HD thread, but I'll say that their CS is still not fantastic. One guy had recently purchased this rear bumper for his truck, and turns out they made a change to the mounting latch to have it bolt together instead of be welded on (presumably to allower greater flexability for difference in manufacturing tollerance across Ram trucks) and they hadn't included the new metal brackets in his order. He had to fight with them over two weeks to get the brackets.Found another solution. This one seems a bit cooler. but it's a full bumper system from Expedition One. It will set you back $3.5k aprox.

I've also got my own tale on their front bumper.
That all said, it's by far one of the nicest looking bumpers (front and rear) that are available. At least to me.
