My software dyno seemed accurate between what I saw for stock WRX before my swap then the gains I got on the awd dyno matched almost exactly with the software runs post swap too.

How accurate it is really depends on knowing the right weight. I wasted time driving around for a bit till I got the gas at exactly 25% and then I made my pretty passenger stand on the side of the strip risking insult about her weight.. All just to keep things the same and even then I know there was a bit of a weight change with the motor swap.
