Alright had an exhaust leak thought it was the Vclamp wasn't seated so I resealed it. Well i also had an exhaust or maybe only leak after the downpipes the gaskets that connect the downpipes to the catback were leaking but that's after the 2 O2 sensors also after this I had boost problems it held to 22 psi and dropped to 12-14 from 5000-6500 rpm which was never a problem... could it be this clamp to close to the actuator arm when I redid it? The arm moves the other way so.... idk if that's even a thing???
