Ahh...beat me to it.
BTW, those 1000cc's are larger than you'd ever need with that setup. Coulda saved yourself some idle issues with smaller injectors. 750cc's can do 500whp no problem with the right fuel pressure.

**** Doh, missed the post about the resistor pack****
**** I'll leave the info here for reference ****
If your fuel pressure is OK and there are no sensor or electrical problem your problem is most likely you are running mega rich.
Sounds wierd, but if you run a engine really rich the car will start to miss-fire, or in extreme cases it stops firing all together. The air fuel meters look at the amount of oxygen in the exhaust system. If your engine misfires, or the spark gets blown out the meter will read lean, even though the engine is pumping fuel out the exhaust pipe. If its not burning the fuel the sensor sees the unburnt oxygen, not the unburnt fuel.
Try leaning out your fuel values just above where the problem starts and come up to the load cells very gradually so you dont slam into any rich parts of the tables.
Good luck.
