What difference does the pop level of the 24 valve injectors create. I have a set that have a lower pop. What change would this make? Would it benefit going to a higher bar injector?

 

The injectors with lower pressure would add more fuel earlier and later than a higher pressure injector but milage may suffer

 

Thank you so much that is precisly what I wanted to know. That would be why the engine has always smoked on startoff and hazed wound up.

One of the reasons that I asked was that I did install regular pop injectors and it seemed to have less power and no real smoke on rolloff.
