car doesn't like 100 shot single fogger, n.o.s. wet kit, 52n 28f jetting.
stock fuel pressure
stock plugs {lil uridium things}
ls4 motor
the car runs just fine on a 65-70 shot {whatever a 46n and a 24f is}
but once it gets jetting up to the 100 shot, it doesn't pull like it should, traps the same mph as the smaller shot.
i don't have a way to log the car to watch knock or fuel to see what it's doing.
just figured id throw this out there to see if anyone has had similar problems. being that there is only a few people spraying the ls4's i don't expect a world of responses.

thats what i was kinda thinking too. i just wanted to get a second opinion from people, or third opinion.
i really don't feel like spending 2 hours to do plugs on this thing

What are your plugs gapped at? I tried running mine at .40 to get a little better on the moter, but when I bumped up to the bigger jets they were blowing the spark out. Get a colder plug and bring the gap to where it needs to be would be my first guess.

i don't think it's running out of fuel. i think it might have to do with the plugs.
being that it's the same injectors and pump from an ls1/2 car, i don't see it falling over on a 100 shot, i see it nosing over on a 125. dunno i could be wrong

im leaning more towards plugs then anything else
gap is stock {stupid i know} pressure is 95-1000 when i make bottle runs.
timing i have no clue actually. it has an agressive all motor tune it, but the timing is well below 30 degrees total advance

If he up's it to a 150 shot won't he pretty much ruin his engine?

By the way area 47, how are you getting away with using stock plug's at all?
I was under the impression that with any size shot, even say a 50, that you needed to run colder plug's.
Is this not the case?

wrong impression. this is the first car i have had, that i have ever gone above a 50 shot. im not new to nitrous by any means. {7 bottle cars in the past} but i am new to the whole going over a 50 on a v8 car {past cars were imports}
