Excellent to hear.
Most importantly, everything went smoothly. How nervous were you beforehand?
155kw at 5000rpm is 296Nm. But that's engine torque translated to the wheels, if you've got 35% driveline loss (that figure plucked from thin air) then you'll have 455Nm at the crank.
Some dynos are smart enough to calculate a driveline loss from coast-down. Others just throw in a rough figure. RWKW is what really matters, you've got plenty and possibly room for more.
