It's probably just the atmospheric conditions between the runs accounting for some of the boost. I wouldn't think that boost could change that much...but there was just another post here about a month back where a guy was logging the same amount of boost changes with different ambient temps. The density of the air can change, and temp is a major factor but not the only one.

I wonder if anyone has ever done a study on atmospheric conditions and how that affects boost (keeping everything with the engine/charger fixed variables). Would be really interesting to read and study. I think that all of us that have forced induction have felt the performance of our cars swing from day-to-day.
