Can i run a 50 or 75 shot of nitrous on a mostely stock 5.3 with the diablo programer? I am afraid the timing might mess with it? is anyone runing this setup? What is a NX wet kit worth with a bottle warmer, guage, swithes, full bottle, and install worth?

 

If you get a wet kit you could just jet the shot rich like I did. I have an NX wet kit with their automatic bottle warmer, nitrous psi gauge, 10lb. bottle and I run a rich 100 shot (100 nitrous jet, 125 fuel jet) and with EFI Live I'm running a 12.5:1 A/F ratio. No knock or audible detonation so I think I'm fine for now. I have a Nelson tune running about 30* of timing WOT with 91 octane.
I've spent about $900 into my setup and I even have other stuff like the MSD digital window switch, TR6 plugs, blow down tube...
Install was easy, do it yourself.

 

I have run a 100 shot with my old Diablo tune with no problem.

 

just run it rich to be safe.....Deckhand on here runs a 125 shot on a Nelson tune w/who knows how much timing....but he runs a really rich shot. Obviously its working though....13.2 in the quarter
