Dan-
you shouldn't have to change 2231 or 2232. factory setting is ok for turbo brake. I have asked Ross once before to edit the table descriptions. They are a little confusing. The end result should be that the ECM will NOT try to control boost, (ignoring the boost table) and referencing the vane table only.

Did you edit the max vane table too by chance!
