My guess would be that you may have a fuel volume problem. Jetting it up on the N/A side would compensate, but it may boil down to the size of the lines you have feeding the fuel solenoid. I would also spend $6.00 on a Moroso spring for the Holley Blue that steps up the pressure and volume the pump can deliver. Moroso part number: 65770...and then set your pressure on the N2O side to 6 pounds, and set the Hobbs switch at about 4.5 pounds. Just keep in mind the weight of the fuel, and what that fuel wants to do when you launch...it wants to go back where it came from.
Have you looked the plugs under a magnifier? and which plugs are you looking at?
