Default i think i mounted my FPSS on the wrong side?

ok here are some pics i just took, is the FPSS suppose to be on the other side of the (IN) side of the noid or on the (OUT) side of the noid?
so what im saying is the fuel line thats running from the fuel noid to the back of the intake ( fp regulator ) suppose to have the fpss on that side?

By the looks of your pic it is backwards. If your wiring it like most people, it needs to be on the side of the fuel source (before the IN). If it's not the system will not fire. However, if your using the FPSS to control the ground for the nitrous solenoid only, that will work the way you have it. That way if the fuel noid sticks shut the nitrous noid won't open.

I don't run one anymore but I really should. If I do put one in again I will probrably wire it to control the nitrous noid ground (putting after the fuel noid). I have never tried it that way but it should work good and still hit good. Most people use it to control the ground on the relay or the ground on both noids. If you use it to control the relay along with a window switch most people will put it between the window switch and the relay.

I always adjusted mine by trial and error but you can adjust accuratly it with an air compressor and a multimeter. There should be some exact directions on here somewhere.

Yes, if you want to leave it in it's current spot (the "OUT" side) you can only hook it to the nitrous noid ground. If you hook it to both niether will fire, if you hook it just to the fuel noid, it won't open but the nitrous solenoid will and you'll have a nice mess on your hands. If your not comfortable doing it like that just put it on the "IN" side and wire it like they normally are.

Not familiar with the LT1 fuel rails but you took the actual schrader valve out of the test port, right?
