What's a wideband setup? It's an S trim. The truck already had the supercharger in it when I bought it. I don't know about the blow through carb, this is my first S/C and I'm just trying to make sure everything is setup correctly so I don't break anything. If you go to the following link you can read the story behind the truck as well as view a bunch of photos:

A wideband 02 sensor, tells you if your lean or rich - it's a good tool for tuning, although you should always read your plugs. But it can help you out certainly if you're tuning it yourself - because you don't want to be lean under boost.

Definately worth it.
