Edge Evolution and SES light

Ok ever since I put the edge evolution in my EX the SES light has come on and shown P0475 which is Exhaust back pressure switch yada yada. I have tried three different switches on known good working trucks to no avail...I have also removed the switch AND the tube and cleaned both out to no avail. If I take the program out and return to stock then no SES what gives???? any suggestions?
