The chain tension adjuster seemed to have done the trick. I used the iphone app to measure the tension before installing them and saw it was way way too low. I think the belt was dropping it skipped a tooth. Today I managed to get to work without any walk or drops. Now I just need to get the SA hub adjusted properly.
And I went with CDC instead of CDX because I got the belt drivetrain super crazy cheap off of c-list a couple years ago. Its been sitting in my parts bin waiting for my to finish this build.
