I don't see 1 dyno being 10% out from another, especially at relatively low power levels.

I think my std A3T did about 95Kw at the wheels, it was 6 years ago.

I take it the dyno place didn't have any other Golfs on file to compare to?

If it goes better than the numbers suggest, don't waste money on dynos if you don't think they are accurate and haven't got a before figure.
