i'd say, no one's right, no one's wrong
dyno: higher power reading doesn't mean faster car down the strip, just shows peak power
drag: depends on car setup(as in 200kw vs 200kw) + driver + condition
ie: one's turbo may spool quicker
in reality, i think dyno is better use, i mean not everyone take's their cars to the drag and has a test, i dare to say more people have dynoed than dragging their cars
having said, the dyno has its limitations as brought up by jaspky: which dyno, dyno mode, wheel spinning
commonn factor would be the weather as its affects both just as much
at the end of the day, some prefer dynos, some hate the dyno queens and go for the drag
who cares?
