There are a few things to keep in mind when dyno testing.

1. Before and after dynos should be done on the same day to keep the weather and humidity in check. Doing a dyno today and then going back in a couple weeks will change these conditions and can lead to inacurrate readings.

2. How does your area under the curve look? You should plot the before and after lines on the same page to look at the area under the curve. Peak numbers are over rated and don't mean as much as the behavior of the power and torque curve.

3. Did you use the same dyno? Was this dyno recalibrated or were the settings changed in any way during the two weeks that you were away? These can also change the readings.

4. etc. etc. etc.
