how does the second stage work?

 

You have to have a second set of solenoids, lines, jets, a couple of y fittings, another relay, a push button, basicly another kit less bottle and feed line. The NX part number is NXEFIDS MAF. That will give all that is needed to make it work.
Those are the parts, now the second stage kit works the same as the first stage does for you now.
Gives us a call if you need anything else.
