David i would bet that with that set up that you are using a little over 3 lbs per pass. Do you not weigh it before or after a run at this point?
We always weight it before and after each pass.

Just for comparison, about how many pounds of N2O are you using if you have a combination like this:
500HP Nitrous Supply annular discharge fogger system:
0.40" N2O jets and 0.32" gasoline jets = @400HP tune up
Running safe rich in the quarter mile for about 6.7 seconds.
How many runs would you make on a 15 PSI bottle, leaving the line at 900PSI?
I have never had an issue using 1/2 of what the bottle will hold, so two runs on a 15 pounder is pushing it with your tune up.
Also rich is not safe, in fact you can hurt it easier being rich than lean. Timing is the biggest killer out there.

Im not sure if others would agree but 4.5lbs a run for a .040 jet seems like a lot. Unless you are starting with the pressure high and purging down.
I was running 2 systems both with .031 nitrous jets when I ran a nitrous combination and I was only using around 3.5lbs a run.
I agree with Al on using half what the bottle will hold. When I ran 1 system I would make 2 to 3 runs on a bottle. With two systems I would change it out every run and that seemed to work ok for my combination. That was with 10lb bottle s though.
