Thats cool Cavy... I would go the safe way too.. that is Why I would do ZEX if I were to go NOS... its the best for my car... But they know alot more about Cavaliers than I do so I would trust them more... Just remember... when you put NOS in your car no matter HOW MUCH YOU WANT TO... Dont put the purge valve on a straw inside the car so you can suck in the extra NOS...
