plate kit

I'm looking into a nitrous setup for my 13 coyote. I was leaning towards adding a nitrous express plate kit. I'll be running longtubes with axle back, E85 and CAI on stock manifold when I do the kit so I was wondering if any of you nitrous guys had any advice for a safe setup.

I have a brand new NX plate kit for a 11-14 5.0 for sale. Its never been opened, I just decided to go another way. Im looking to get $600 plus shipping. if using Paypal please add fee or send as gift. Same kit shown here at AM http://www.americanmuscle.com/nitrou...ekit-1112.html Kit retails...
