Anti-Defueling-Device (A.D.D) - What is it? Do I need one?

[Kyle]

Anyone know what this thing is? It sounds like it's an electronic boost "fooler" that goes on the MAP sensor. Is that what it is?



Anybody got one? Your opinions?



Thanks,

Kyle

That's what it is. If you're stock it won't do anything. If you add injectors or a box then it will make your truck so it doesn't notice the extra boost. They do work. There's a bunch of different brands and usually if you get a "box" or "chip" it will come with one already built in.
