Nothing wrong with getting a fresh tune on new skis, but having likely owned 100+ sets of skis, it is my experience that 90% of factory tunes are fine. I am yet to not have a good factory tune on Nordica or Blizzards, which has been the majority of my ski purchases the last 10 or so years.
This is my first K2 ski in probably 20+ years, but this experience will probably keep me firmly in the Nordica/Blizzard camp moving forward.
P.S. - My newly purchased $199 STP Liberty Evolve 90's had a great tune right out of the wrapper. All I did was detune tips and tails slightly (as I do with all new skis) and they performed flawlessly.
