What else do I need and what else SHOULD i get for it? pressure gauges, purge valve, what? And what is up with the purge valve, do you need one and when do you use it? Also, if i'm only going to use it once in a while, do i need a bottle heater, or at least a blanket? Any tips from NO2 users would be greatly appreciated because i really don't wanna go blow up my car or break the no2 before i can really get to use it. Thanks guys.

Go one heat range colder on the plugs just to be safe and back your timing down some. I ran a 75 shot for a long time on the stock pump, so you'll be fine there. If your thinking about stepping up to a larger shot and I know you will, you'll definately what to add a bigger fuel pump. As far as the regulator, the stock will be fine, it will increase your fuel pressure as you spray it anyway.

I never ran a purge valve, I just hit it a couple of quick times in the waterbox to purge mine out. A bottle heater is a good investment, for cool nights and the winter months.

You can run a 150 shot safely on a stock 5.0 with a little more fuel and some timing pulled, so I wouldn't worry to much about a 75 shot. To give you an example, I did spray my 75 shot one time before I got the rpms up and the only thing it did was blow a vacume hose on the back of the intake, it didn't even have enough to blow a headgasket. I'm not saying thats what would happen all the time, but it'll give you an example.
