I know most people say convert to mass air and I will eventually but my budget is maxed out on the Vortech, Cobra intake with tmoss ported gt40, aeromotive 340 pump, drag radials, torque box plates and a few other things. Some speed density owners get away with 24 lb injectors and some don't. I am a little worried about 28 yr. old 19lb. Injectors with the Vortech. It seems to me 21lb. Size would be a perfect fit for now. What do you guys think?
