First a little back story. 2013 3.5, Turbo bypass solenoid has been replaced, BOV replaced, Cat less down pipes, 91 performance tune, NO CHECK ENGINE LIGHT and no stored codes. My tuner says that my truck is over boosting and that their is very little WGDC. Has anyone had this issue? Anyone have any ideas where to start looking? I really don't want to keep throwing parts at it.
