All it does is tell the Ecu its running Less boost to avoid boost cut. BUt the ECU runs enough fuel to make about 225rwkw ON stock injectors with the voltage clamped @ 4.18 volts.
4.32volts is actually the boost cut threshold. ANd most adjust to 4.25v to completely avoid it/
I tried so many different voltages on the dyno.. Tha main issue is not fuel related, But by reducing the voltage to the ecu. It actually runs more ignition timing. So its the advanced timing which makes it ping, not the lack of fuel ( as we tested ).
Ive since fitted a Blitz Ecu and @ 17psi made almost 240rwkw on stock turbo's and running out of fuel with the stock injectors.
