negative preasure egr system

OK the ongoing saga with my egr valve , i guess my exhuast is too free flowing for the negative preasure system in my car , Im going to have it converted to a positive preasure system , where the egr doesnt need to have back preasure from the exhuast. now i was just wondering if anyone else has had this done , My car runs super , hell it passed emissons yesterday with flying colors.

The positive EGR is the one that requires back-pressure.
