If it at all possible, you should take a brisk 20 minute ride with logging software before you dyno tune. That would give the tuner a great baseline to look for changes. When you dyno tune only, the PCM is tuned to improve max performance only. As you drive the PCM will compare the changes made and make subtle improvements to all of the intermediate paramaters every ten minutes of drive time. That is why it may take a few hundred miles to really notice performance increases.
