With that 2 dyno run's it doesn't really mean a lot, first of all the car hadn't had time to adapt learning to it at all, and 2nd that 2 dyno run's back to back can alter 5rwkw's or more, particularilly if you drove the car in dyno'd it, and then put cold air intake in and started it and dyno'd it again, heat soak sets in amongst other things, also the
ecu has a startup map that it run's for a little while after starting which depending on engine temp takes a little bit before it turns off. Many dyno tuners will actually do 3 run's back to back each time when fine tuning because of this, that way they get more consistant results if you were to look at the 3rd run each time.
