Granted perfect 0 degree phasing would be ideal. But if the phasing was causing the issue it would vibrate on accell as well. Shaking on decell sounds like the pinion is to far down. That being said your angles dont add up. Trans down 2 at the rear. axle up 2 at the nose is zero. Where do you get the 3 degree pinion angle from? What am I missing?

Sorry about the confusion. I had a brain cramp. I corrected my previous post to read correctly. I'm 2* down on both the tranny and pinion.
When my Charger was like that is was not good at any highway mph cruising, I now have it,,,, trans from right to left, 2.5 down, Pinion 1.5 up with Caltac's set 1/4 " loose so the pinion can come up a little under cruise conditions to match the Trans angle, when I go racing, my preload on the Caltacs makes the Pinion go to 1 down & so far that has worked great.
