how is the system going to reference how much fuel is needed? if you don't increase the fuel when you shoot the nitrous through it, you A) will never be happy with your purchase, B) will most likely not feel any difference between stock and with the nitrous system, C) may actually cause harm to your motor. remember, fuel makes power - nitrous just lets you burn more fuel.
a "dry shot" doesn't add any fuel to the system. that would be ok if you upgraded your fuel delivery through your injectors. otherwise, there is only one way to go and that's with a wet shot. a wet shot brings fuel with it, so you get the extra fuel you need for the amount of nitrous you are adding to the equation. there are two hoses running to the plate, one from the nitrous bottle and one from your fuel system.

These are three basic types of nitrous systems: dry, wet, and direct port. The most misunderstood is the "dry" type of system. A "dry" nitrous system simply means that the fuel required to make additional power with nitrous will be introduced through the fuel injectors (remember, fuel makes power, nitrous simply lets you burn more of it). This keeps the upper intake dry of fuel. We accomplish this by two methods. First, is to increase the pressure to the injectors by applying nitrous pressure from the solenoid assembly when the system is activated. This causes an increase in fuel flow just like turning up the pressure on your garden hose from 1/2 to full. The second way we can add the required fuel is to increase the time the fuel injector stays on. This is accomplished by changing what the computer sees, basically tricking the computer into adding the required fuel. In either case, once the fuel has been added, the nitrous can be introduced to burn the supplemental fuel and generate additional power.
The second type of nitrous kit is the "wet" style of kit. These kits include carburetor plate systems and add nitrous and fuel at the same time and place (normally 3-4" ahead of the throttle body for fuel injected applications or just under the carb as with plate systems). This type of system will make the upper intake wet with fuel. These systems are best used with intakes designed for wet flow and turbo/supercharged applications.
