Turbonetics Owner Get Together....
Many of the mustangs are running return fuel systems from the factory..depends on the year and engine type. I agree....FI without a return system is a poor idea.
What you are missing, is there will always be a pressure drop at the injector nozzle, that is precisly the amount of boost you are running. Running 10psi results in an effective 10psi pressure drop across the injector. This is the reason for a rising rate FPR. Yes, you can run larger injectors, and tune around it, but its less than ideal from a tuning and safety perspective, and means you have to run potential excessively large injectors to compensate. Larger injectors can result in poor idle, part throttle, and tip in conditions.
