I have the dual shark jets from NX. I bought it from Nitrous Dave's last year. I am very happy with the kit but once I got it on and played with the jets the car seems to load up when the nitrous hits. For the jet sizes I am using the chart that came with the kit. I also have a wide band and a hand held tuner. My ? is does the kit come with jets to make it very safe if so does anyone have the right size jets to use or part numbers.

 

Different combos may require fime tunning. If the system is rich you may need to go lower smaller on the fuel jets. What is your airfuel?
