help!!! ok so I wired in my nx kit today and during testing I noticed that at about 5 grand the car falls flat on its face and it feels like it only has a 50 shot on it (150 was added) car also runs way lean when spraying. new plugs (ngk tr-6) and plug wires are only 1 year old. fuel pres is about 55 when I'm wot which I have noticed is about normal. also ses light came on flashing after test. I'm lost and I have no clue as to what the hell is wrong with it. help!
Dave is asking you the actual PSI of the bottle. Also how do you know the car is lean? Going lean in the middle of a run will deffinatly make the car fall on it's face. Are you running a stock pump and, did you get a look at the fuel pressure gauge when the car falls on its face?

bottle pressure was at 925-950 a/f guage wasn't even reading it was so lean came back into visability after I let off. the fuel pump is stock but I am using a wet kit to try and counteract that. the fuel press was sitting at about 55 when it leaned out which is what I noticed to be the normal fuel pres at wot. Is there a possibility one of the selenoids are wired wrong i.e. the fuel one?
What all is done to your car.It sounds like you may need a fuel pump.Check the fuel solenoid first and see if it is working.Take the line off of the nozzle and aim it into a can.Then take and bump the nitrous system on.If you have a window switch take out the activation switch and run a jumper wire in its place.Check to make sure fuel comes out.What jets are you using?

I don't think your getting any fuel either. Even my Walbro pump will drop 3psi or so when spraying a 150 shot. When my car was getting no fuel from the solenoid the O2s would hover in the .800s for a couple of seconds then drop like a rock. I would check that noid like Dave said and check the jet and nozzle for any debris.

ran all the checks it's not the selonoid. I'm thinging it might be jetted wrong. either that or I dunno. I'm almost to the point of taking it into someone to fix. but not quite yet. The car is a straight bolt on car stock engine, etc. exhaust is longtubes ory loudmouth. intake is ram air slp cai kn lid 85mm maf stock tb ls6 intake. has tr6 plugs and msd wires. I'll keep on it and try to get it workin right thanks for your help so far I'm sure I'll be needing more.

Always check the simple stuff first.. Or just be careful when you're putting everything together in the first place..
Glad to hear you got it figured out.. Lucky you didn't do any damage..
Dont you mean your car was running Fat? If you had the bigger Nitrous jets in the fuel line, and fuel jets in the nitrous, you would have way too much fuel in your motor...
it was probably not taking the Shrader Valve out of the fuel rail
