Reviving this thread out of curiousity.

What would happen if you removed the butterfly disc without doing anything to the EGRs/mapping?
Surely it would massively reduce the amount of gunk coming from the EGRs????

No it wouldn't, it will still flow into the engine.

Yes I agree that it would still flow but if the butterfly is not closing it must be at a reduced rate?
