You will be injecting approximately 3000cc/min of fuel. Assuming you are running M50/W50:

1) Without nitrous:
3000cc/min x 20% = 600cc/min.

2. With nitrous:
3000cc/min at 30% = 900cc/min.

I suggest running 2x 1mm nozzles. Use one of fuel rail pressure compensation input to tell the HFS-4 to rasie the injection rate from 600-900cc/min, approximately 50% extra.
