At only a 75 shot nitrous would only sputter. (Have test light wired into noids) Bypassed FPSS at WOW magic. Steady and bright light. I think a fuel pump is needed to be ordered. Is this what I need. The high pressure right?

P.S. That was 75 can't wait to try 150.

 

A better fuel pump is never a bad idea when running nitrous, but it's possible your FPSS wasn't adjusted correctly. This is fairly common from what I've seen on this board and others. As far a a new pump a lot of guys seem to go with the Racetronix since it's such an easy install.

 

Sounds like you just need to adjust the FPSS-
If it is set to a cutoff point that is the same as your pressure, it would cycle like that- just a slight adjustment should through it to a point where it doesn't cycle but if you start to lose pressure it cuts out-
