I took my n20 kit off months ago, I was having problems with the fpss before I took it off, is there anyway to test it before I put it back on the car? I have no clue as to where it is set at now. Thanks

 

There's probably a variety of ways... you could plug it into an air compressor set at the pressure you want, then adjust the FPSS to trigger at that point. You could plug it into your fuel system with a gauge, and watch the pressure drop after the motor's off, and set it to trigger at the pressure you want (would only work for a wet system, I guess).
