You will want a window switch, heater, bottle pressure gauge, and a purge is a good idea as well. Don't rely upon the Zex nitrous management unit (NMU) to keep you safe. It will read wide open throttle really early. I had it on my 2006 and was staging the car - prestaged, purged, then brought the rpm up to 1800 to stage. The NMU read that as WOT throttle and fired off.
You don't want to spray before 2400 rpm. When you start spraying lower is when you run into issues.
For cool evenings, and early and late racing season you will need the heater to keep the bottle pressure up.
A 75 shot is safe, and many people running a 100 shot even. Any higher and it is riskier. And nitrous is really a track only power adder. You can't run around on the street with it turned on all the time because it will wear down the solenoids, and the nitrous tune is a compromise for daily driving; you can drive on it but performance will be off without the nitrous. Plus even with a 75 shot I could only get about 10 passes on the bottle before pressure was a problem. At $4-5 a pound for a refill it isn't something you want to be running around armed and ready all the time.
