I believe that I am starting to feel some misfires at full throttle - not every time however. I am starting to wonder how I diagnose. After testing it out again during a track day in two days, I am thinking of going back to the stock tune to see if it happens then - and if so, I will roll some dice and take it to the dealer. Thoughts from the smart people reading this thread...? I have 7,300 miles and always run the same 93 octane fuel - perhaps I should wait a tank before updating the tune which I will take care of during my next track event...?
