LS2 injectors ?

[yellowC6ohio]

What are the LS2 33lb injectors rated at I have heard 43.5 and 58 psi
even then the values given by the calculator are way off compared to the stock numbers
if I set the calculator to show the rated fuel rail pressure to match the actual fuel rail pressure (65 psi) I get figures that are a lot closer to GM's


is there something we are missing ?

how many people have changed their settings to reflect what the calculator says instead of the stock value? what is the major advantage to doing this. have you noticed any difference? power, response, fuel economy?
