Huey,
If you had a tune made specifically for nitrous, it should have timing set to an appropriate level. My understanding is that OP's tune is just a 93oct NA set-up which would have timing increased and that would be a NO-NO with nitrous. I just wanted to be sure if he had a 93oct tune, he would know not to run spray with it.

I was woundering if you need a wot box and an rpm box so that the nitrous turns on and off only at a certain rpm?

You should absolutely have a WOT switch on your system to prevent activation at partial throttle. Any decent kit will have one.

Adding a window switch to control the rpm range it will activate in is a GREAT idea, but not required. I strongly recommend one to prevent catastrophic engine failure from accidentally using nitrous while hitting the rev limiter. This can happen VERY easily in low gears or any time you lose traction.

In the heat of the moment, it is easy to do bad things. To be safe, make sure your nitrous set-up won't let you do anything harmful to your motor.

GOOD LUCK!!!

i have a 04 cobra and i was woundering what size shot i should use

This question is really TOO GENERAL to answer.
We need more details about the nitrous kit(wet or dry), what other mods you have now or plan to add and what you hope to gain from using nitrous.

Get a ZEX kit!

Activates at full throttle, get a window switch to keep from poor user activation, bottle heater to keep correct pressure for the right mix (pressure affects how lean or rich the mix will be) I have a 125 shot with a tune with no issues. 91 octane I get 350rwhp/450rwtq Nitrous

After everything was said and done with dyno tune $800 Install is very simple, American muscle has a video that shows how to install it, takes about 2 hours if you take your time.

i want a wet shot and i have a 2.8 pully, bassini catbakcs, slp midpipe and dyno tuned

pballer12,
With the forged bottom end in your car, you can run a fairly decent sized shot but you have to tune and monitor your A/F closely. There is a point at which you will run out of fuel with the factory pump (this is probably your first constraint).

If i was planning on running nitrous i would definley get a different intake..The plastic intakes dont like nitrous..
