I'll look at my jet chart when I get home, but this seems like too big a fuel jet for your nitrous jet
At the Nitrous Express website they have a jetting chart broke down by vehicle.
I'm running a 150 shot and am using a 62n and 36f on a single nozzle system.
do you have a pressure gauge on your bottle...or a bottle warmer....I'm wondering if your bottle pressure is spraying too low and your fuel levels are to high for the amount of NOS your spraying, that, combined with projection tip plugs that have the effect of advancing the timing may be throwing things off.

Have you actually checked the plugs to see what its doing?

this is the thread i made when i started doing plugs.
the next time i went out after checking a few plugs, the car ran horribly.
so i gave up for a few weeks while i was working on other stuff.
i discovered last night that its only the left side running lean.

got a fuel pressure tester and tried no nano with standard jets. car still breaks up, and fuel pressure drops down to 40. i'm trying to find a new pump by the weekend so i can still go to the track.
but im also wondering if the solenoids might be pulling to much of a draw and the fuel pump is losing flow. i cant find anyone else having the same problem with only a 100 shot running out of fuel. so it leads me to believe my stock pump is on its way out.

flow your bottle, you can do a 10 sec count wo a jet and it should release a certain amout of n20. Weigh your bottle before and after. That will tell you if the N20 is doing its job. You also as you have been told, put a fuel pressure gauge on the car to see if the fb is dropping. Its not that hard to figure out if you take the right steps.
