I think somewhere back a few pages I might have put a photo of the jet chart. I know I did a lot of research on the jetting two years ago when I first installed the system. Over this past summer, I re-evaluated the numbers and made some slight adjustments. I went to Bruce's and bought a few more at that time.
Aside from looking at the pre-determined charts on some of the reputable nitrous vendor's websites, I also used the robbie-the-robot internet calculator.

The fuel pressure is 65 almost all the time, and looks like it drops a few psi to maybe 60 psi during the run (as seen in the above go-pro videos). I hadn't found a jetting chart for a single stage single jet plate with 60 psi of fuel so I had to make my own numbers.
This is my quick reference chart, but I also have one that is more expansive
All that being said, I am not sure that the jetting is really the issue, as you will see in my TnT writeup soon, I kept those same exact jets in, and went extremely lean instead at the track! wild
