Hey there! First post here. I have a 2017 focus st. Two nights ago I put on a blowoff valve (turbosmart) drove that night worked fine. Drove the next day all was fine then. Drove this morning still fine. Went for a drive again today (first time on a highway, but not my first time getting to highway speeds) and now when I build to 8lbs of boost I get a really rough popping noise from my car and it bogs down. I’ve taken my blow off valve off since made sure everything was right and it was.
