Did you get the complete C&C kit (motor/tranny/wiring harness/ECM)? If so, the tune should already account for FPR. The stealth pump should provide more than adequate pressure to minimize any variations in the fuel pressure due to the distance of the FPR from the fuel rails. If you were wanting to go with BIG HP, I would recommend installing a return style fuel system with the FPR close to the rails. Let me know if you need any help with the tune, I've played around with the LS3 a little,
