Okay so I have been reading the Nitrous thread for a while now and im highly considering this for track purposes, but im a safty freak.... Do I have this right...?

Musts:
1. TPS
2. MSD Window
3. Cooler Plugs
4. Bottle Heater (not a must but needed)

So here are my questions...
1. What EXACTLY does the TPS do? And does the Zex kit (probable getting Zex) have a built in one?
2. So i set this to spray during 2500 - 7000 only.... Will it continue to spay in between shifts while the RPM's are still kinda high even though im not on the gas for that second?
3. How many stages cooler...? And im not new to N2O, I had it on my old car, and a lot of it, with all the proper fuel upgrades, but I kept fouling plugs and so have some member here, is this a reoccuring problem and how do I stop it?
4. I have read it's a must to keep your bottle pressure up around 1000, but is this totally nessicary, and what happens if I do not have a heater, will this harm my engine, or will the nitrous hav eno effect?

This is what im considering... Zex wet kit with purge and bottle heater with MSD Window moduel.... Also I am going with a 5 LB bottle if possible, I do not want the bottle in the hatch to advertise, planning on in the glov box....

Any advice and answers are greatly appreciated.... Thanks

 

Also I would like a fuel pressure gauge and Nitrous Pressure gauge, but Can i mount these in the cockpit liek on a piller pod or not????
