Symptoms of a bad wastegate?
Just wondering what the symptoms of a bad wastegate are, I think mine is going out. With my boost controller turned all the way off, I go WOT and spike 18 psi then it's almost like I'm feathering the gas...goes from 18 to about 5 then back up to 18 then settles at 13 which is the base pressure on the wastegate spring. Any ideas what this could be? I'm going to completely unhook the boost controller and run the wastegate to the compressor housing and see if that fixes it. Anyone know where I can buy a tial rebuild kit for my wastegate?
