A dyno will always read HP and TQ in appropriate amount. HP= (TQ x RPM)/5252. They stick to that. But one will read more than the other cause differences in other places.

DJ's read HP and calculate TQ, DD's read tractive effort (TQ after gear ratio's and mechanical advantages are applied) and calculate into HP/TQ.

Roller differences, strap down differences, math applied to the reading differences, calibration differences. Add them up and things aren't always the same.
