I was going to start my own thread, but I guess this is probably the best place to ask as well.
Has anyone tried Klotz additives like their Nitro or Coxoc, but with an EcoBoost application? I read a test done years ago on the Fox body Mustang where they dyno'd some decent gains with the Coxoc additive (about +20 hp mid-range). The Nitro looks like it might be really great for knock resistance at the track.
