Default Fpss

Can someone help me? I am going to buy a fpss but i need one that will cut off the nitrous if the fuel press drops below 58psi right? Where can I get one, or who has a part number so I buy the right one. I tried doing a search but came up with no solid info.Thanks

Most FPSS are adjustable so you can set it where you want it to be. Adjustments are made via a allan key and twisting it left or right. Below is a link to our FPSS:

Good choice on using one. Hopefully I install my NX kit this month, and I hope to get the FPSS dialed in.

Lot's of peeps had issues with them, but I am determined to get it functional.

You're right, some people do have problems with them. 99% of the time it is due to not having them adjusted correctly.

Yup good question, I know there's a lot of trial and error. Which is where many have given up (no patience?)

I don't have the instruction sheet in front of me, but it's roughly 5psi per one 1/4 turn right??
