I'm a little confused. Maybe you guys can explain something.

Lets say we are using a dyno to measure the TQ of an engine. This works by what? The wheels turning creating a certain force? Now if the wheel size was increased would the TQ measured change? If the gear ratio was changed on an S2000 say from 4.1(stock) to 4.44 what happens? They say the 4.44 is like more TQ at the wheel

Why is engine torque even advertised?

[B]Some time ago I read about how a dynamometer works... let's see how good my memory is...

A large drum, of known dimensions and mass, is under the drive wheels, supported by low-friction bearings.

which is determined by engine torque.

Exactly! Torque -> Acceleration... not HP!
