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.

Almost all dynos will automatically correct results based on weather conditions to ensure that results are accurate despite being taken on different days. You are right, though... the area under the curve will tell you if you have a faster car or not.
