Default 39lb injectors

I just got them in and i am also going to have an svt focus fuel pump soon should i wait for the fuel pump to install or should i wait for the entire turbo setup, or would it be ok to install now with only coil pack upgrade and wires plus the windstar swap.?

Wait. Adding them now will require a tune, and 39 lbers are huge for an N/A set up.

thats what i thought but my buddy that is helping me with the build was asking.. I have a diablo tuner though but i don't think i want to be running that rich.

also the injectors are the "big blue" so they are more along the lines of 42lbs <-- as says some web sites.

39lb blues were also sold as 42lbers..... max flow rates are similar.

I did some decent beginer mods so far (in my sig) and I really feel like my car is craving for a dynotune, but I'm still not doing it, I don't feel like spending $600-700 without anything major under the hood. Maybe soon, if I get the SSM pack!

BTW what's canned tune? Is that the one with the tuner only?
