I'm torn on what to do myself. Right now I've got an AEM wideband in my blank spot, 3 pod under dash(half works), and a crappy tach on the column. I go back and forth on the different dakota sets. With the LQ4/4L80E, I like the idea of the HDX's but not sure if I can justify the money vs the VHX. Even those are pretty pricey. A lot of the time I bring a tablet with me and connect to ELM through bluetooth. I'll use the torquepro app and can moitor dang near everything. I am tempted to build a cluster to house a tablet and go that route. Not sure how I would address the fuel level though.
