Nitrous fuel pressue info needed

What does the instructions say on ur kit..... I run 9lbs with a 500shot on my duster.on my 09challenger rt I spray a 75 shot with stock pressure and timing...



I would say 6.5 is a very good start and take 1¤ of timin out it should tell u want pressure to run and how much timing to take out with each diff size shot.... Or just go to zex .com or nx express.com they should have charts there
