jetted crossplate on dyno nos jetting way off 44nos 45 fuel used 55 nos and 45 fuel made extra 100hp on top of what it made previous and still running way rich on the dyno

an equivalent jetting to a 300 shot would be in the 66n and 58f on both ends of the crossbar, and i would run it with between 6.25 and 6.5 fuel. your a/f will have alot to do with how you jet the carb also, the way my old setup was i always ran teh carb a little fatter to prevent detenation on pump gas driving on the street and could lean the nitrous out a little bit with no worry with the race gas... worked out well for me...
