Ok, I need to question something, because I'm not sure I fully understand what's being done here.

Are you using the EGR flow to enable lean burn under normal circumstances, or are you using the EGR flow as a "filler" to lower effective displacement?

I would guess that with a variable valve, you're doing the latter.
