I stopped by the mustang store here in town (Carolina Mustang) and asked some questions about nitrous. He said that the had a Compucar kit (compucar in a bag) for $360. He said that a dry kit would be the best for my car b/c it requires no tuning and you can just put it on and go. I really want nitrous BUT I want it to be as safe as possible. So.. if I recall I dont remember him saying that I would need anything else with this kit to make it safer, he said that the car would automatically retard the timing when it notices the nitrous etc. etc... Help me out with this one guys.
