Newby to nitrous fuel system and setup
All that was wrote is fine and dandy but if you are looking for more than a 75-100 hit you need to first and foremost learn how to read plugs and plan on a AFR if you want to not make a mess of things....
Reading your combo tells me Spray was not a consideration during the build. A little is OK with minimal changes but if you want bigger hits plan on backtracking your combo.
I am a huge fan of NOS. No different than adding headers. Power adder plain and simple. A little is easy and alot is somewhat involved to make it work in all applications....
