if your bottle is oriented like this, than you need a tilt angle smilar to mine.
the wb is never the only measuring tool you should use, especially if you don't have tuning software to data log. reading each spark plug should be your reference to gauge how well the w/b is working. if i was spraying huge shots, than checking the plugs is a must.
the n2o noid draws a lot more juice then the fuel noid and, so, if the circuit is not a clean one the n2o noid will have trouble opening where as the fuel will not. i'm a nitrous rookie and these are the problems i have had.

lol, yea in this case I see a HUGE back fire and parts flying everywhere...

Agreed on the full bottle statement. I understand the limitations of a wideband however checking a plug in each cylinder for this issue doesn't quite make sense. Making sure that each cylinder is running correctly, absolutely agree this is the proper method. It does not explain why a 75 to 100HP shot would cause the issue I'm seeing. It's a relatively small increase in the shot and overall it's pretty small for such a big difference in the way the car is running.

Where should the A/F be if all the plugs are looking like they should?

Car has a FPSS but it would shut down the entire system, not just the nitrous noid. I have a racetronix pump with hotwire kit and fueling is not an issue which is monitored by an electronic fuel pressure gauge.

Again, I'm going to switch back to the 75HP jets and see what happens. If it runs clean then I'm really going to be confused as it just doesn't make sense why that would work and not the 100 jets.

SPRAYIN96TA - I do not have problems taking the car to a nitrous specialist however I don't believe the symptoms will be easily repeatable unless done track side.

Please don't take comments as I'm arguing but simply discussing the possibilities of what's going on here. Bottom line is nitrous is not flowing like it should right after the launch and I think it may be a leak somewhere or lack of flow somewhere in the system.

That things gonna come ALIVE down low when you get it figured out. I wouldnt spray it again unless your test firing solenoids to find the problem. your asking for a backfire

You may want to run a test light on your solenoids if you have a delay you have an electric problem may even be a as simple as a ground.
