Gas saving device

Sir,

assuming it leans a/f mixture (which saves fuel consumption), you also mentioned earlier in this thread that the ECU still have its O2 and manifold absolute pressure sensors to correct A/F... sir di po kaya the device helps the entire Fuel System achieve STOICH levels at any given state (idle, high speed, braking, gear shifting, etc) of the engine?

Why spend hard earned P6500 for your engine to reach stoich levels when it can do this even without your device since you did say that it does already have all those sensors to adjust itself. Why introduce a purely mechanical device that has no feelback system into an already balanced machine?

BTW, not all cars are equipted with a closed loop ecu.
