fuel pressure for nitrous...

That is the way I have always done it and it has always worked for me. I used 47n and 53f most of the time. I picked up at least 7 tenths in the 1/8 mile. 7.20's to 6.40's. It varied because of traction issues. 5.5 lbs fuel pressure.

I think you should read over what I quoted then read what you posted. They are two different things therefore you saying "that's how I do it" then claiming you use a different fuel pressure (7>5.5) does not make sense.
You don't flow a kit through the plate or even through the solenoid. You don't even need to activate the kit to flow it. I learned my ways from a pro and use over 100lbs a season, I'm not just posting because I like moving my fingers.
