What kind of correction factor is your dyno operator using? On our local dyno they don't correct for anything but humidty, and we are at 5000ft. On Cobb's Mustang, they do run a correction factor, as they are also at 5000ft, and that is part of the differences in the numbers beyond the calibration. If those two dynos you tested on run different corrections, then that could explain why the Mustang, which does generally read higher, is reading lower than the Dynamics. And did you run on one on a 60 degree day and another on a 90 degree day? There really are a lot of variable that could explain the discrepancy...
