Personnally I wouldn't use copper, it will corrode quite quickly with the chemicals and heat from the exhaust gas. I have done this with a piece of 1.5mm S/Steel plate, then filed the end of the connection on the EGR Valve down to allow for the blank. Have not done anything with the vacuum hose, my theory is that if the blank works as it should, the valve will not let anything through other than the cold feed from the intercooler. I have noticed a difference in acceleration from this.
