Im not stock, I have exhaust and headers and a little bit of head work done with a bigger throttle body, not really sure of all that would make a difference for injector size though

19 is fine... You will throw off the ECM if you put in 22's and don't tell it... It can adjust fuel within a certain degree, go with the 19's... I have a 305 TPI and bought my injectors form SouthBay too... no problems...

what Rafael said, even if you put in a bump stick it will not warrant larger injectors. Bosst wel thats a different story.
