Nitrous fuel pressue info needed

I run the fuel pressure the same as the carb! The pressure is not as critical as one would think at that low of a hp shot. Tune it to the fuel pressure with your o2 sensor. In my street car I get it in 3rd ( with a co-pilot watching the read out of the o2 sensor ) And I hit it. adjust till your happy with the tune...and then do it again. This time when you hit the spray run it up alittle and kill the engine. coast to the side and pull a plug for Reading if the plug looks good you can trust your o2 guage and should be able to use any time you need it! Also you should use a regulator on your nitrous! NX makes a good one! 900 psi is where I tuned mine at. Bottom line is set your line pressures and tune to your o2 guage. Oh yeah mark my words if a 60 shot feels good than 100 will better...if 100 feels good than 150 will feel great...Its an addiction!!
