Right uk300 wrx I want to put sti injectors will this gain bhp thinking pink injectors? Had a vf36 turbo already

 

it may do depending on fuel pressure,a regulator with psi display to show true pump pressure would tell u if injectors are maxing out, at high boost levels. mapping would show this. on ecutek im not to sure if it would.but if changing to pinks a map will get the best out of there running.
