i just baught the motor. its got i/h/e victor x mani, crower retainers, aem cam gears, n zex spark plugs, from what i can see. the cam settings are: intake pos 3, exhaust neg 2.

i want to run nos. i know that i should set them back to zero then work from there, but the motor pulls real hard all motor and i dont want to lose that. now for the question, i was wondering if its ok to spray on this setting and how much of a shot can i go. any help would be appriciated
