I have 1050x injectors with my air-air Si supercharger setup. Was going to order a return fuel system from CJM but Charles thinks the G37 coupe may work best with the 350Z/G35 fuel return kit. Any inputs? Waiting to get a hold of Seb at specialtyz about tuning availability and I’m planning on going flex fuel right away. If I started with returnless, I assume I would also need a re-tune after going returnless?
