I put the NX Jet sizes through the old spreadsheet and found some patterns
which can help you with the jet sizes. It's nothing scientific, but when I
called up NX, the tech didn't deny the pattern.
The difference between the N20 and FUEL jets is a factor of 2 (odd numbers)
starting at 15 from the 50HP shot:
HP = N2O/Fuel (Difference)
50 = 35/20 (15)
75 = 41/24 (17)
100 = 52/33 (19)
125 = 57/36 (21)
150 = 62/38 (24) - This difference is why I think we're running too rich.
May help you with the jetting.

I'm running very rich with the .38 jet as well, My A/F guage gets pinned in
the rich when I hit the switch. I was gonna upsize the N2O jet though:o)
DAK99RT went a little leaner and noticed a big gain as well. I was looking
to tinker last night but not only did one of my fittings spring a leak and
my bottle heater break but I got rained out too:o( (wasn't my night) Let me
know what you think of the MSD retard box as I'm looking to get rid of my
jacobs.
