You can look at the history of my install thread to see how long I've had the turbo: http://jeeplab.com/showthread.php?13...bo-DIY-Install

First stage 1, then stage 2. Keep in mind that I'm not an experienced installer, so some of the tweaks have simply been corrections to my own mistakes. Other tweaks have just been personal preference.

Sounds like you might possibly have the O2 sensors installed in the incorrect locations? You should have transferred the O2 sensors over to the same exact relative locations from the stock pipes to the turbo pipes. It's a bit confusing because the colors of the sensor's connectors are opposite on one side of the engine (white is upstream on one side, black is upstream on the other side). Need to make sure that the sensors themselves are in the correct locations, and that they are plugged into the correct connectors.
