I need fuel psi directions, and any other info that would help.I've tried every thing.

What is the problem?? Missing, backfires, burned spark plugs, fried engine?

Well, I run a single holly blue fuel pump. I run a 1/2 inch line from the fuel tank, and i tee into two holly fuel pumps. one for nos the other carb. I run 5 1/2 flowing on nos and 4.5 on carb. It pops on the high rpms mostly. Can you line me out from start to finish?

It sounds like you are going lean on a cylinder or two.
Is this a "fogger" system or a plate under the carb to feed in the NOS?
What jet sizes are you currently running?
Are your spark plugs new and a cold heat range? Are all the other ignition parts up to the task of "lighting-off" a much denser (and harder to light) cylinder load?

I run a fogger type system with #20 NOS & #22 fuel jet with 5 psi of flowing fuel pressure. I use a MSD 6A, Blaster coil and copper core wires to make sure the charge gets lit.

I'm running a nitrous works plate system. My plugs are 2 stages colder that stock. Fuel jet is 52 and nitrous jet is 47 for 100 hp. I use accell super stack coil and accell 8mm wires and the stock magnetic pick up distributor.
