I know you can use the ZEX nitrous kit to mess with FPR pressures to get more fuel out of the system, but I don't know exactly what it does. I do know I couldn't get it to work properly with my system. The stock FPR is very sensitive though. If you really want a lot of adjustability and flow, I'd suggest piggybacking a secondary Fuel Management Unit (basically a tunable FPR) into the system. That's how the BBK s/c kit works. All my tuner friends with various vehicles tune their fuel systems this way, with a standalone or piggybacked new FMU.
