Turbo and stock fuelpump

im going to be doing it... untill i can get my hands on some GTS injectors. then ill be upgrading my pump.

now is it ok to add the GTS injectors and get the fuel pump later on--or should they be added at the same time?

C2 stage 1 uses stock fuel system.

I'm running stock pump on my gt-s so far so good.

Is the gt-s pump better than the gt or is the same?

I had to upgrade my fuelpump (also have gt-s injectors).
My fuelpump couldn't deliver, especially when boost kicked in, so I was running mad lean (1:19 !!) and in higher rpms it got a bit better (1:15) but still too lean. upgraded fuelpump and all was fine.

i just bought a PE fuel pump last month.

I'm running stock pump and already putting around 260whp with under 12 AFR till redline..Its holding OK. No plan for change..

Do you have your wideband O2 readout? Because that is what the necessity is based on.

I can add so much fuel that there is black smoke behind car,and smells of gasoline.

Mabey it is because that i have 8 injecters??

doubt it, think of it as having 4 huge injectores if the pump cant deliver the fuel the injectors cant add more fuel because their is no more fuel to add, best way to check if you need a bigger pump is to install a fuel pressure gauge if it falls you need a bigger one

I dont need bigger injecters.I can add enough fuel.
