Well I now have eliminated all of my KNK LT Retard, and most of my KNK ST Retard (1.0) around shift point. I did this by changing form the 93 CAI tune to the 91 CAI tune, and increasing fuel 5% across the board. I think I will try to reduce the 5% by increments of 1 till knock returns, then increase by .5% in order to get the optimal setup. Richer, but not to rich, with no knock. Any other suggestions, or am I on the right track?
