I just bought a AEM UEGO on ebay. The install was so simple and I love it. It gives me accurate, immediate readout. I plan on putting a video camera on the gauge during a run, so that I can keep my eyes where they need to be. Then, replay it to see where im at. During my first run, my cruise was at an AFR of 10, I would have never guessed that without it. I can already tell how useful this tool will be.
