Ok I topped off half the tank with 91 octane along with using the water remover and Chevron fuel treatment. I put about 20 miles on it and the chatter is still there. I also changed the curve to all in at 3000 rpm along with adjusting the total timing to 34 degrees. at idle i'm at 14 degrees.
Unfortunately the chatter under load is still there. Here are 2 videos I made of the noise.
