I have been using NX for about 9 months.
It is the most reliable system I have used.
I have been through about 50 bottles with
no trouble whatsoever (not counting tire spin).
I have seen lots of naturally aspirated cars
backfire due to puddling in the intake. It would
be extemely rare if not impossible in our applicaton, as we are forcing the Nitrous through
the intake with hurricane force. No puddling in my intake.

You must change the plugs of course. And I closed the gap to .035, I think the book calls for .044. That will keep you from blowing out the spark. It has been awhile, but I think for the NX kit and the GenX2 kit (purge, bottle heater, bottle gauge, fuelpressure safety switch) a must have, is about $900. The kit is adjustable from 50-150hp. I got my kit and install from
