ehhh well I know for sure up here in some local shop they plug the wideband where one of your o2 sensors are. Just screws in right in place. I've never been to another dyno so I dont know how they do it. I though they all did it like that.

Yep, I've heard of that being done too. The two dyno's I've been to and the portable dyno I saw at a NMRA race had the sensor in the tailpipe. I think I'd rather have the sensor screw in the O2 bung in case you had a small exhaust leak downstream from the header.
Yeah, the 02 sensor bung makes more sense to me too. Some shops can weld in another bung, helpful if you want to do part-throttle tuning with a power adder. Not necessary for WOT N/A or Nitrous pulls, however, they don't use your stock 02 sensor at WOT anyway.
EJ's Dyno shop in Omaha where I've gone a couple of times, he will tap in and read stuff like fuel pressure and water temperature if you want him to. Pretty high-speed place, lots of knowledge too.
