How accurate are the AEM UEGO widband A/F meters?

How accurate are the AEM UEGO wideband A/F meters? The reason why I'm asking is because after getting my truck dyno tuned when I get on her from the hole and run through 1sr and shift to 2nd my A/F meter is buried at 10 and the engine bogs a bit, but on the dyno she read 11.5 to 11.8 solid all the way through the rpm range. The truck was dynoed on a Dynojet.

Should I go with the AEM reading or the Dynojet reading?

Go off the AEM, its in the pipe itself, unlike a sniffer thrown in the tailpipe. It doesnt sample as fast as a dynojet WB would, but I think it would be much more accurate. I have one in all three of my cars and go off of them to tune, even when on the dyno with a wideband. Does your truck have a front mount air to air intercooler or is it a water/air like the other paxtons?

Its the Water to Air intercooler it just has a bigger pump and heat exchanger.
