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?

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 had the same issue but after the pump and the injectors everything was A ok

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.

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

 

[Toyota T23]

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