A Scantool isn't needed for the open loop tuning that BlackSunshine916 will be doing. It might be a benefit to do closed loop tuning, but it isn't necessary.

The Wideband O2 has nothing to do with what is already installed in your truck. It is a gauge that you will use to measure the air/fuel ratio, so that you know whether to add or subtract fuel at various engine load levels.

You really should read the URD U-Tune Guide, but ignore the closed loop tuning and fuel trim stuff. Also ignore the ignition timing section. You'll only need to do the Open Loop Tuning. Keep re-reading it until it starts to make sense, THEN start buying the tuning tools.
