Dipping a toe in the rabbit hole...

It allows your boosted Z runs more reliably and "consistently" under WOT no matter what fuel your using. For FF, it's definitely a MUST in order to keep the pressure on the fuel rails truly regulated, thereby making each of the injectors outputs equally regardless of their position difference. From my experiences, the injector duty drops by almost 20 percentage after the RFS was added (gas). This significaly alleviates the loading of the fuel system. As a result, I see no reason that anyone choosing to go forced induction should not include a RFS for our car IMO. You may save some for now money but you may spend more in the future. Especially you can save a lot of labor fee if you have it installed along with your charger kit. Installing all of them at the same time is much cheaper than installing them separately.
