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...

Hmmm .... according to the horsepower equation (seen several times way earlier in this long discussion) .... a measurement of torque on the crankshaft resulting from the explosions in the pistons is required. Where - and what kind of - transducer, somewhere in the engine or driveline is providing input to the scanner so it's logic circuits can calculate horsepower output of your engine?
I'm open to being educated on how vehicle manufacturers would pull off this kind of measurement. Maybe a centrifical force gauge, or an inertia gauge, could provide calibrated torque data for inputting to a scanner?? An interesting "instrumentation" issue here.
Torque Sensor
They are used in a variety of applications. Turboprop engines use torque as a primary power setting parameter.
I agree with transamz9 that a computer program given the right data specific to a particular engine could come up with some sort of HP calculation based on fuel flow and RPM.
