Hello, I just got my Nitrous Express kit installed and it work great before and while i am spraying but after i let up the car dies. It will start right back up i just want to see if anyone may know what the problem is. It has the 120hp jets installed using a dynotune box to spray betreen 3000 and 5500 let me know if you need any more info. Thanks for you help in advance

 

What is your air fuel while spraying. It sounds like when you let out the car is taking on all the fuel in the lines and rails causing it to die.
