Horsepower is horsepower?
If that theory is true (in real circumstances), then a 385hp 6.7L Cummins diesel shouldn't spank a 381hp Toyota Tundra when both are tested 0-60 towing a 5740# boat. But it did. Must be the adva...

A pick up truck with a diesel engine rated at 400 hp @ 2900 rpm and 800 lb ft of torque @ 1700 rpm will will pull very similar to a near identical pickup truck with a 6.8 l V10 gasoline engine rated at 362 hp @ 4750 rpm and 457 lb ft of torque @ 3250 rpm if both trucks have the same transmission but the gasoline equipped truck has a 6.73 rear axle ratio vs the diesels 3.52. The gasoline engine will put power to the rear wheels at the lower rpm range and the diesel more power to the rear wheels at the high rpm range.
Shouldn't that last sentence be the diesel at lower rpm, the gas at higher rpm?!?!?!??? Otherwise I would agree if at sea level. at 10K feet elevation, the 6.8 will be sucking for air! unless it had a forced induction intake,ie super charger, then both should be about the same up to 10K' or so when a turbo/supercharger start to wain in power levels at 2-3% per 1000' elevation gain as a natural aspirated rig will.
