timing issue?

[stamper5.0]

soo today i just put adjustable fuel pressure regulator on and set it at 40psi at idle. (i think that is good?) but i was wondering what my timing should be. i have it at 12* adv. for motor. how many or wat degree should i put it at when im spraying. and im only spraying 100 wet shot.....

I have no personal experience with nitrous but I know your timing should not be advanced to much. The base timing for our engines is 10* You should be safe running it right there. Hopefully someone else will chime in.
