when using this gauge do u need to have another hole drilled and tapped for the oxygen sensor? i know u cant just tap into the 03+ ones.....

If you have an actual Wideband....it has it's own special o2 sensor, in which case...yes you would need to have another bung welded in for that sensor.

If using a narrowband gauge, it does not come with a sensor, so that type you just tap into the wire on your existing sensor.

sorry to being this back up from the dead, but im installing a LTH with has 2 bungs already installed...where does the stock O2 sensor go, and where does my Wideband o2 sensor go?? top or bottom??

As long as they're both in the collector I don't think it should matter. I wouldn't think alot would change in a few inches of flow. An open header may be a different matter...IMHO anyway.

The wideband should be installed before the cat for best results.

Wideband should be installed before the Cat. The downstream should be after the cat.
