Can the stock wastegate be modified by drilling and tapping a port underneath the diagphram area of the wastegate? Would that make it a the same as the dual port type ? I do not see wy this can not be done ? I do not think the small holes already there lead into the housing? Anyone try this yet ? Or can the new port being added just be hooked up to the boost line to hold the wastegate valve controlled for higher boost ?
