I had a 3 inch exhaust made and the guy who made it put the dump tube back in the exhaust pipe but he drilled a half-inch hole for the gases from the wastegate to flow thru and just welded the dump tube over the hole. Its a Tial 38mm with a 10.5 spring. A half-inch hole isnt big enough for gases to flow through? My car was over boosting dramaticlly, and thats cause the hole wasnt big enough right?

Thanks just wanted to check my knowledge, I tried to convince him to cut the hole the size of the pipe but he said it was plenty of room for the CFM's for that to flow, I said, its not an N/A car, turbo is different, its pushing the air out, not flow freely out.
