Dts dynos are known to provide lower (slightly) HP figures.
I recken the torque is not the raw figure, but the converted figure according to SAEj1349 standard. I think the assumptions or friction calculation done by the dyno shop has something to do with the abnormal torque reading.
For some reason the dyno does read slightly lower figures. We had a dyno day (supra) and pretty much every single car showed less than expected. Mates supra was supposed to pull 470kw. Got it up to only see 411kw. Fair bit of difference, hub dyno to this dyno.
