As I understand it, an EGR block off will effectively eliminate future CBU (the reason people have undertaken this task) but also creates more exhaust soot (not getting burned up in the EGR cycle). Me thinks that you have to go all or nothing - all being EGR block, install DP in place of DPF and sooner or later gut the cat associated with the SCR. The tune can also code these systems out to avoid SES lights.
I guess you could get a tune and leave everything intact, but you would still have the possibility of CBU down the road.
