IF EVERYTHING IS WORKING PROPERLY YOUR WASTEGATE HAS NEVER OPENED IN ITS LIFETIME (NO WORRY ABOUT WEAR).
THE WASTEGATE IS ONE OF TWO PARTS DESIGNED TO PROTECT AGAINST EXCESSIVE BOOST.
THE SECOND PART IS A PRESSURE SWITCH ON THE MANIFOLD,WHEN THIS SWITCH CLOSES A SWITCHOVER VALVE ON THE FIREWALL CHANGES POSITION AND DUMPS BOOST PRESSURE FROM THE ANEROID COMPENSATOR,THIS REDUCES FUEL QUANTITY TO THE ENGINE.WHEN FUEL QUANTITY IS REDUCED SO IS BOOST.
