When it comes to NOS, I have three pieces of advice:
1. You need two bottles.
2. The big ones.
3. Oh, and you need it by tonight.

LOL sorry I had to

In all seriousness, here's my advice for running N20 in your car:
If you can afford it, get a direct port kit.
If you can't, get a DRY system that ups the fuel pressure when spraying, and keep it to a 50-shot or less.
Do NOT run a wet kit on a modern EFI engine! EVER! The intake manifold will not flow the fuel evenly and you WILL get lean cylinders.
Don't underestimate tuning with a piggyback to increase safety and power when running nitrous.
Make certain that you are running one or two step COLDER spark plugs.
Make sure you're running a high performance fuel pump (Walbro 255)
