K I've been thinking about putting the zex nitrous kit on my car but had some questions.
1- It says that the nitrous is activated at WOT. does this mean that it comes on as soon as u stomp it or is there still some sort of button or switch u use to activate it?
2- Will the GT kit work on the v6?
3- Is there some sort of special tune u need for nitrous? Or is a dyno necessary? Or is there something I could just do on my own w my xcal 3?

1-what you do is wire in an arming switch. What this allows you to do is leave the system off, but when you get ready to use the kit: flip the arming switch on, make sure you're in the right range to take advantage of your nitrous (too little you won't get the same hit, too much you run a GREAT risk of causing VERY bad things to happen), if everything looks good, purge your kit so that you get the air out, when you begin purging some nitrous (you'll see it come out) you're ready for it to give you the extra juice.
2-as far as i know you CAN use the same kit. HOWEVER, the one designed for the V6 will start at a 35 shot, and go up to a 75 shot. the kit for the GT will start at 75 and go to a 150 or 175 shot (can't remember for sure). This would be why you're better off with the one specifically for the V6.
3-you definitely want to take and have the car dynotuned or street tuned. You want absolutely no guessing when playing with nitrous or any kind of forced induction set up. period. So no a dyno isn't necessary IF you can find a reputable street tuner. A dyno just allows you to do it in a controlled environment and not have to get out on public roads and worry about being able to pull the car up to 110 mph or so for a decent pull to tune with. You might also want to think about getting an air/fuel ratio gauge as this will allow you to monitor if your engine begins to spike to the lean side, which would allow you to know to get out of the throttle and get the tune tweaked ASAP to make it 100%.

So after i hit the switch the nitrous will kick in whenever i hit wide open throttle?

right. assuming that you've purged all the air out of your nitrous line. If you haven't you'll have no hit for a moment until the nitrous finally makes it way to the motor
k and another question on getting your car tuned for nitrous. If ur car is tuned for the propor air/fuel ratio w nitrous wouldn't it be wrong when ur not spraying the nitrous?

just to be safe, when you get the kit installed, put it on a dyno to atleast good you an A/F reading on the nitrous so that you know for a fact that it's not running too lean on you. If it does go lean, shut it down and call it a day, go home, call the closest reputable tuner and see what they recommend for a hand held (or if they specialize with say SCT and offer and handheld and tuning package), and get it set up to get the car tuned with the nitrous.
the whole idea with the fuel and nitrous line both going in together is that you're already adding the extra fuel you need with the nitrous whenever the kit activates and gives you the shot so that your original A/F shouldn't really change at all
