I am thinking about upgrading my 3.9L v6 injectors but I would like to keep the rest of the fuel system stock. I know I'll have to get a tune with it too but I didn't know what size injector to go to or if it was even a good idea.

Why do you think you need to upgrade your fuel system?

You have 21lb injectors stock, thats more than enough for the mods you have.
