at WOT I feel the nitrous kicks in around 4 grand and it is pulling strong, but then once it hits 5500 it kinda dies, then when I shift and the and the rpm drops back to like 5 I feel another kick but then dies down again as the rpm rises. Does anyone know what's wrong with my nitrous kit, or my car for that matter.

 

what car is this on? are you sure that ur FLOORING the throttle? do you have it wired up to a window switch or something? cause mine kicked in whenever i floored it, not at like 4k rpm. give some more info like what car it's on, what shot, etc

 

what are your power sources and grounds?

 

I figured out the problem, my nitrous line has a puncture in it, so I was losing pressure, that's why it would kick in and then let go.
