elevation difference ???
Your relative loss of power is slightly less than 4%. You have the slight advantage that your air is probably colder and less humid on any given day, offering a litte more power.
Another cross check is to log your runs and check the KPA at WOT. I went from 150 to 7000ft the other day and went from 100 to 88 kpa at wot, about a 12% loss of power.
I would assume the dyno software correction or whatever is fairly accurate.
FWIW.
