I called a NX tech a few weeks ago about a 75 shot for my 03 G35. He told me to go with a 41N and 23F, so those are the jets I bought. Recently, I saw on their pdf that 50-55 PSI fuel pressure call for a 41N 23F jet for 75 shot as provided below in the link. Searching thru this forum, people recommend 41N 24F jets for a 75 shot for NX. Will I be ok, or should I order the 24F jet and wait to spray?

This is what I use for my calculations:

What I would do though is buy a bunch of jets up and down, if you take a look at the following thread:

Some are not exact so you need extra jets to dial it in. Do you have a gauge to monitor your afrs?

 

I do not have a AFR gauge. I plan on buying a AEM AFR gauge and tapping into my kinetix test pipes that I just bought.
