ykobayashi - thanks so much for the detailed post!

I will pursue the things you mention.

One thing I don't under stand is this: "Then I decided to cut the locknut on my rack damper bolt down 0.060” and adjust it in a bit. " - can you or somebody give me a bit more info on what you are referring to?

I think that it would be ok to totally bypass the switchover valve between the manifold and the ALDA, right? I've seen where some folks have done this.

Also- there is another device that hooks to the alda- it is a blue plastic item with 2 vacuum lines that is attached to the driver side wheel well. I wonder what this is for, and if it is needed.

I'm fond of the idea of simplifying the vacuum lines as much as is reasonable. And I think I'll do the ERG delete.
