That graph is inaccurate. Clearly you can see that power was sampled at only a few points then they connected the dots. Notice how in the low/mid range, the ford shows less torque than the duramax, however it miraculously has more horsepower at the same points. Since horsepower is a mathematical derivative of torque, it's mathematically impossible for that graph to be correct. It's very misleading, as they just line through a few points on the duramax's graph and make it appear that the powerstroke outpowers it for the majority of the mid-range, but that I doubt that is the case.
