what do u guys have your fpss set at. I set mine at 40 psi and was running what everyone else is running there's at?

 

i dont use 1,havent used a fpss in 8 years. never had any luck with 1,always cut on/off no matter what we did,so i just gave up on em.

 

I agree with RacinLT1, mine did the same thing. Just make sure you have a good fuel pump.

 

the reason i ask is I just installed one on my car and now my nitrous doesn't work. My car was surging when i ran my last bottle at the track. It was about 50 degrees outside and my bottle pressure was around 750-800 psi with a full bottle I just replaced my fuel pump this month and also installed a bottle heater this weekend. i guess i'll bypass the fpss and give it another shot.

 

surging is the reason I took mine off too. I have had it off for about 8mths.
