J DAWG, I run a 150 shot with my set up. I dynoed 605/689, at that level I recommend a bigger fuel pump to be safe. I'm still trying to figure out some symptoms my car has, it starts up real rough during cold starts. I think it's fuel pump related because when I crank for second and than try to start, it starts fine. If you have a vec2, make sure you have a card that retards the timing for the nitrous. Last thing, don't forget to run colder plugs.
