I think common belief is that powerstation gives low/spot on values.

The figure you have might be bang on, but I would use +/- 5% as a buffer. I say this because rolling roads can only be used as a guide, there are so many variables its not possible to get a very accurate figure. Sure, if you spent lots of time doing lots of runs you could prob get close to the actual figure, however the only true way to find out the power / torque output is to put the engine on a calibrated dyno bench and even then that will only tell you the output for the conditions that are present at the time of the run, i.e pressure, temp, fuel, etc etc...

Some tuners are now going towards a half way house with their hub mounted dynos, which from what I heard are quite good.

Thanks guys I hoped that was the case, I always bear in mind the reading may not be perfect but was worried mine cud be massively down.
