DA and 3w use dynos to establish power output.....

I'm not lauding either of them but the point is accuracy matters. The issue isn't just DLA, it's all the manufacturers that post HP values without ever actually using a dyno to make those determinations. We see numbers everywhere saying so and so engine makes X HP but there is no basis in fact. It's all conjecture.

So the question was not directed specifically at DLA engines, but really applies to all of them. DLE, MLD, CRRC, etc.
