I need some help with my nitrous system I have a 340 that has a cheater 250 shot. .093 nitrous and a .102 for fuel jets. I haven't used the system in a long time so I filled the bottle, checked my flow, pressure, made sure the solinoids were working. When I activate it the motor just starts crapping out on me. made sure i had the right plugs, and retard my timming. everything by the book, So whats left? Thanks Tom

 

Sounds like fuel delivery. Is it falling on its nose when the system is activated? The engine runs fine without it? What type of fuel system are you running and what type fuel?
