yep sounds like a very happy dyno or more so the operator was fudging the figures
305-310 rwhp would be more realistic
The mathematics behind why a vehicle shows more power when it is allowed to completely come off the rear roller is due to the fact that the Inertia of the Rear Rollers are accounted for in the dyno software, so if you aren't actually driving them, you do get something for nothing.
The Inertia of the rear rollers of the dyno you probably used, would equate to at least 20Nm at Ramp Rate of 10KPH/sec, and if you add 20Nm or roller torque to whatever value it is at 258RWKW, it will become 273RWKW.
