if i get the walbro fuel pump for my y reg wxr do i have to change the injectors? and will i notice a difference with the fuel pump without changing injectors?

so far i have cat back, induction kit, and front mount.

thanks

 

standard injectors will out supply fuel required by standard turbo.

You really need to get the car setup and remapped.. you can't just chuck fuel in and expect more power..
