Follow the directions and make sure your fuel system can handle it. Also you might want to start off with something smaller instead of just jumping into a 150hp gain. Make sure yo have the right plugs and log all your runs to make sure you dont run into any detonation.

I know this is obvious, but you're asking for advice and you know I cant refuse 
The two major concerns are going lean or activing it at too low an RPM (or leaving it running at too high an RPM). The standard precautions against this are a fuel pressure safety switch (to keep it from going if the fuel system cant keep up), and a window switch (to keep it from activating at too low an RPM or staying on when you shift).
A better (Ie, even safer) solution than a FPSS would be a NX Maximizer, because it watches your O2 sensor instead of the fuel pressure, so it's more of the "bottom line" regarding whether you're lean or not. IE, the FPSS wont protect you from a faulty solenoid or crap in the fuel line, or if the nitrous pressure is higher one day than when you tuned it.
The NX Maximizer also works at a window switch.

> Ok this may be an idiotic question but can you not spray throught the gears in an auto with a 3000stall? I wont be sprain til 2nd gear.
With the stock trans, I dont think it will take 150 through the shifts. Mine couldn't even take the engine's full power. The stock PCM tune removes several degrees of timing on shift to keep the trans alive. When I disabled this safety function my trans started slipping on the 1st->2nd shift.
This safety function probably pulls about 40 ft/lbs at most. You're talking about adding 130 ft/lbs at your shift point (150hp @ 6000 RPM is 130 ft/lbs). Based on my experience, I dont think the stock trans will take it. Who knows, maybe my experience is not typical and others will chime in.
You can definitely improve the trans to where it can take it, but I assume you dont want to do that.
If you put a window switch in you can set it to stop spraying just before the shift and start again in the next gear. This will help a lot. Unfortunately, a typical window switch isnt smart enough to do this right and it'll start spraying before the trans is done shifting. Might work fine, might slip.
Once again, this is where a controller like the Maximizer has big benefits. You can program it to cut off before the shift, then wait a short time (.2 sec) before it reengages in the next gear to give the trans time to complete shift.

I have a NX wet kit on my 2004 GTO and love it...make sure to get it dyno tuned, my car was super rick and popped and even had a fuel backfire before we got the jetting sorted out. Before tuning, drag radials, and computer mods, I ran 12.5 @115 with just the bottle....should be bottom 12's at 118 or so I would imagine.
