Promise you what happens is when you loaded the new tune, adaptions are reset and that accounts for a good chunk of a gain like this where your initial power is low. My bet is you have a ton of miles on your spark plugs and have never changed O2 sensors? Drive for a week and dyno again, I suspect ypuld drop right down to within 9hp of your base pull
