2007 Porsche Cayman — dyno numbers changed more than the car feels

2007 Porsche Cayman S, about 96,000 miles. Two dyno sessions on different days show a noticeable power difference, but the car feels the same. How much can temperature, correction method, tire pressure and dyno type move the result?
