All of my hoses and piping from turbo to IC and from IC to intake are all new and tight. Had over 5k on them before my tune was adjusted and had no issues prior. Now since retune I'm getting P2188 about every 70 miles but it took almost 800 miles to start getting P2188 after the retune. I can't figure it out... Anyone have any suggestions?
