Well also, i don't know if this is a problem or not but i know some people when they install the Vacuum hose from the Wastegate and they connect it to the nipple on the Turbo. What i did to my wastegate vaccum soure is that I connected that Vaccuum source from the Wastegate together with the Vacuum source on the BOV (with a "T"fitting) and then i connected to the Engine Vacuume sore, i don't know if what i did is right or wrong.
