I do however have some questions.
1. What is the complete list of purchases I need to make? I have seen tuner packages with the tuner suite and a wide band from tuningschool, but that by no means that is all I need. And yes I have a laptop.
2. Can I plug the wide band o2 into my rear o2 ports in my kooks headers and just leave them there for the life of the car? If so how do you wire the sensor in to the cabin?
3. I would like to have a gauge pod on the A-pillar at some point so if there is a package that will somewhat match a quality boost gauge that would be great as well. If I was to run gauges then which ones should I run with?
All help is appreciated and before you mention it yes I plan to use the home school method with the tuning school.
Thanks again

Along with tuning and scanning software package, such as HP Tuners, I highly recommend a WB02 kit. Of course, you already know that. There is a steep learning curve especially how to use the software. Its not that intuitive. I am still learning some features of the scanning software.
In my case, when I was calibrating the VE and MAF tables, I simply put the PCM in open loop, set the PCM commanded AFR to 13:1 and ran around recording the AFR % error and changing the tables until the commanded AFR and actual were withing 1-2% at all RPM and loads. Then reinstalled the NB and put the PCM back in Close Loop. If you go to HP Tuners website, you can download instructions how to do this.
Its a good idea to have a separate O2 bung welded into a header collector just for the WB02 because for the PCM to run in closed loop it needs to receive a signal from the NBO2 sensors. Because the NB and WB output not the same voltage, you simply can not substitute the WB for the NB. My PLX WB02s connects to a dongle which has an output at the NB voltage so it is possible but I would have to modify the original NB wiring harness or connector which I was not willing to fool with.
If you want to install a permanent WB gauge, then just add the bung to the header. The passengers side seems to have enough room.
I learned by reading the HP Tuners fourm. I had a mentor in town who I could call and ask questions. I also bought up Greg Banish's book "Engine Management Advanced Tuning" at Barnes & Noble. You can order it on-line, too. I consider this a must have book as it explains theory and the process of tuning.
Good luck.
