kind of a dumb question.... what does a wideband do??

The only accurate way to measure a/f ratio.

We install these gauges (they come with an O2 sensor as well) on every turbo/charger we do.
They are very critical to have.

Also, if your truck is a head/cam combo or high rpm running truck, a wideband is very important as well.
