Flowing fuel pressures???????
I'm running a 300 shot, fjo mini controller, direct port, and stand alone fuel system. NX recommends 10 lbs of ffp. Now with that much fuel it pegs my friends wideband (rich). We are down below 8 lbs now and its still very rich. NX claims that 8 lbs will make it very lean but the wideband and plugs say other wise. What do you guys run your ffp at? I'm sure the right jets are in it (according to NX)and all of them are clean. What should I do? Put smaller jets in it or less fuel pressure?

Something seems wrong since you jetted lean and still pegging the WB rich.
One other thing to check is if your ignition system is up to par. Weak sparks blow-out making a wideband falsely read rich even if the tune-up is spot-on. Since you are running a good sized shot that shouldn't be overlooked.

Well thats what we thought originally. And found out that the noid wasn't working correctly (nx lighting series 1st gen). Sent it back and they did something but it didn't make any differance. So we put on an older noid that I knew worked fine and all is well except a/f was super rich. How would I test for the nitrous to be flowing correctly?

Little update. Just pulled off the intake to check jets sizes and for trash in them. Everything was clean and right size (31 nitrous/ 24 fuel). I'll tear apart the noids next.
