Not sure what the deal is, just got my beast out for its first long run this week. 100 miles of Interstate. After about 90 minutes of driving I started to get some crazy bad ping. This afternoon I fired it back up and it was still pinging cold. Not sure wth is going on. Running 9 degrees BTDC, plugs are clean and gapped. Not happy with the mixture after the head has gone through its break-in?
Thinking about throwing a tank of Premium in it just to see, only things I can think of are mixture and octane. My wallet is already crying at the prospect.
