Direct Port Jetting Size
Given that the stock fuel pressure on a 4th gen fbody is 58ish... On the chart the fuel jet is "N/A"... Does this mean i dont need a jet or that i have to either:
A. Run a 200 shot
Or
B. Use a fuel pressure regulator and jet accorrdingly.
Input and sound advice are always appreciated!

Yeah you may be to small I think even at 200 I was told it's better to run low pressure because the risk of something getting stuck in the jet is higher with such a small opening.

U need to run 55-60PSI jetting chart for stock fuel pressure 4 generation
for 200 shot for nitrous 26 and fuel 14
for 100 shot for nitrous 20 and fuel Not Available it's best to contact NX to give you the jet size , N/A in the chart doesn't means without jets , Because it will runs too much rich .

If you want to run a lower HP jet on a Direct Port, I recommend dropping the fuel pressure so you can run a larger fuel jet. You can do so by either using an independent fuel pressure regulator or going to a dedicated fuel system. If you go with a dedicated you'll get the added bonus of being able to run higher octane fuel when spraying-

If I were to run a fuel pressure regulator, and wanted the 150 shot at 5psi, what would be the correct jets?
