ok so ive ran the bbv with no lower hose solenoid removed and an L fitting on the FPR so its all taken out and it was like this during my tune....i put it back in the other day and i seem to knock less is this just coincidence or is it actually working?....my pcm doesnt pull fuel with torque managent any more with the tune....just wondering i would rather not run it just because 1. it can go bad and cause boost issues and 2. it removes more clutter under the hood
