2 bottles, -6 for the direct port, -4 for the zex kit.
I guess my biggest concern isn't quite the 2 kit problem yet. I'm more worried as to why the 250 shot jets didn't make much change and why its was sooooo rich. I need some way to figure out if the spray is restricted somewhere or if ignition cant handle it or what? What else could it possibly be?

maybe the -4 line from the noid to the block is limiting your nitrous?
putting bigger fuel jets and lowering the pressure pretty much bruings you back to where you were.

I agree on the fuel thing, what that shows to me is the nitrous is the limiting factor somewhere (or ignition, no1 has still said anything about this)? My question really on the low fuel pressure thing was is it ok to run it that low? I know people run low press systems, but this regulator has the high pressure spring in it.

I was uner the impression that a -4 should handle 300 hp?

I always thought -4 was good till 200?
As for the fuel, I don't think it matters what pressure you run it @ as long as your AFR is always there.

i'll tell you that insufficient bottle tilt will affect how dense the exiting flow is, which in turn will result in a rich mixture at the end of the track on a transverse mounted bottle. my bottle is mounted across the car not fwd to aft. the bottle was tilted 16deg. which i thinks is industry standard, i reconfgured it to 35* and the goin rich at the end of the track problem was solved.

i logg all my runs, i know for certain that if you install a bottle across[sideways] it will have that very result, going rich at the top if the tilt is the standard 15*. it was especially worse with the nano sys. that i installed and progressively worsened as the bottle was used up. i usually got one good clean run with a full bottle and then it went south. with my new revised tilt of 35* to 45* , my problems are gone. you may want to investigate the capacity of the noids and or the tune, i bet it's a comibiantion of a few things.

You my friend, just gave me the courage I need to hit my car with a 200 shot. I've been trying to dial in my n20 setup and I keep going pig rich. I went 10.0s with 100pills, 11.0s w/ a 100fuel and 150n20, so instead of lowering the pressure in the stand alone and staying with the 150 like I originally planned, I think I'll just put the 200nitrous jet with the 100fuel and see if that gets me spot on.
