i think the stock FP for a 91-91 350 tpi is about 42 psi. I want to run the 100 or 150 shot of NOS and they say the fuel system should not go below 25 psi when the NOS is activated(with the stock fp setting). Would bumping the fp to 50 PSI give me so insurance ?

 

Stock pressure would be fine and will make for a more accurate air/fuel ratio and more power from the nitrous kit. It was designed and jetted for stock pressures. If you want some "insurance" install a fuel pressure safety switch on the nitrous system. Be sure to get one for EFI fuel pressures (30-40 PSI) not for carb pressures (4-6 PSI).
