what is Dry or Wet set up? There is another...
However you can't go a huge shot (i think 125 is the most that you can be safe with, and event hat you can have problems). If you max out the injectors you wont be able to add enough fuel and kaboom.
Wet kit is more plumbing but you have more control of how much fuel to add to the car. This setup sprays nitrous in after the MAF and the fuel solenoids add fuel
