The HFS-4 is PWM-valve system (same as fuel injection), based on fuel flow and manifold pressure. You can use two nozzles (simplier) or 6-nozzles direct injection (complicated).

Questions:
1. What is the fuel injector size
2. Is your nitrous a dry or a wet type.

Once I have these answers, I can advise nozzle size.
1. #52 injectors
2. Not purchased yet, will be a wet setup though.. 50-100 shot
