fuel pump\injector question

[paxton350]

ok im getting rid of my msd and paxta map systems and am having my pcm tuned for my paxton sn2000@ 8psi on my 94 lt1 z28. i realize i need larger injectors and fuel pump. i have ls1 28.8# injectors on there, would those suffice or would it really make a difference to go to 36# injectors. im also installing a walbro 255 lph fuel pump, what im saying is would i really need those 36# injectors with the walbro fuel pump vs keeping the 28# injectors with the walbro and tuned pcm. thanks

You will need larger injectors and 36# would be your low side choice. The tuner for the chip would be the one to ask since they have probably burned chips for others with 8psi. Just remember the Paxta Map was adding a additional 40% more fuel at WOT.
