Having a few probs. with the juice here and I think its the fpss. Its set from factory at 35, I dont have access to a pressure gage and was curious if somone can give me a "ballpark" figure on how much it will turn the pressure down with like, say, one full counterclockwise turn. Bout half scared to bypass it altogether. What would be to low of a pressure setting?

I wouldnt want to go lower than the 35 setting.....get you a gauge and check it, it may be faulty.

I wouldn't necessarily trust the "set from the factory" number. I put the FPSS in a "tee" on the line from my air compressor, and adjust the air pressure with the regulator, then check the FPSS with an ohmeter to make sure it is opening and closing at the pressure I want.

I also wouldn't go below 35psi if your fuel jetting is based on stock fuel pressure of 43.5psi. You should not be much below that at WOT, or you have a problem.

Another thought would be to wire a pilot light or LED across the nitrous solenoid, so you have an indication in the cockpit that the solenoid is actuated, and will see the light go out if the FPSS is causing it to shut down.
