fuel pump or injectors

is it better to get bigger injectors or a bigger fuel pump???

im having trouble choosing what sizes i should get.

thanks

Get a fuel pump if you don't have anything to control the bigger injectors. If you get a 255lph fuel pump or larger you will need a AFPR. The size of injectors you want to buy depend on what you are going to control them with, and your turbo.

Go with the pump but figure out what your goals are first. If you want lots of power get the 255 and AFPR together, otherwise a 190 should do you fine.

i dont think this is a problem that needs diagnosing...
