You need to know what the bottle pressure is. Did the car feel like it was running strong, then nose over? Could be a few things if that is happening. Especially if you're running a FPSS.

You need to track weight used per pass. That way you will know if you are firing full power.
Could be a clog, and you're only getting part flow. Looking at the plate can fool you.

Again, a clog could feel weak. Are the plugs super rich all of a sudden?? Less N2O than usual.
Could you have a delayed trigger issue?? Hitting after you're already rolling??

I wired in a small indicator light to the power side of the relay(pin 87) that goes to the solenoids. So at least I know when the solenoids are getting power to spray. Helps me see if the system worked during a run instead of wondering "did it spray". I can see when my delays and my window switch works on my microedge.

The light is a good idea. I even have one on my Pro-Mod, because of all the trouble I had last year.
I took a mini warning light I had laying around & tied into solenoid feed also.
