Samco hose does, or we do a bolt on dump valve that goes direct to atmosphere from turbo

Small Turbo cars NEED a RECIRCUATING dump valve, as the airflow meter has already told the ECU how much fuel to put in for the mass of air passing through it. No dump valve at all and the air goes back through the Air flow meter, and causes over-fuelling, due to the same air being calculated for fuel wise twice. An Atmospheric dump valve means air that is meant to go through the engine goes straight out to atmosphere, and the fuel that has been added by the airflow meter just pools into the intake and again can cause rough running and overfueling.

My car is the test bed for the MSD EEC IV 350 BHP conversion, and one of the vital modifications is making sure there is provision for a recirculating dump valve, and personllly I would NEVER run no or to atmosphere dump valve as the car will never be 100% without a recirc
