Thats about it I think.
Yep, that's about it.

Step-1 is a set of PEMs (programmable memory modules to replace the EPROMs for LH and EZK), if you want to send your ECU boxes here I'll install and test them for you (no additional charge). I should also be able to copy the maps from the EPROMs if they were Sharktuned by Devek.

Step-2 is a WBO2 sensor. This can either replace the stock O2 sensor or be installed in a second threaded "bung". For example most X-pipes and some headers have a bung on each side-- one for factory O2-sensor and the second can be used for a WBO2. Or replace the factory O2 sensor with the wideband and connect it with a ST harness kit (included with ST2, available separately, or roll your own).

If you're going to buy your own Sharktuner then a "black-box" WBO2 (no display) is fine, ST provides the readout. The Innovate LC-2 is a good choice, currently $150 from Amazon. If you won't have ready access to a Sharktuner then a WBO2 with a display would be a good idea to keep an eye on things, the Innovate MTX/L would be a good choice. The challenge here is finding some place to gracefully mount the gauge.

Step-3 is Sharktuner, either buy your own or borrow one or hire someone to tune the car who has one. Colin for example is a wiz at this stuff, and I suspect he would be available to travel for the correct inducements.

Connecting Sharktuner is easy, just plug it in. The learning curve varies greatly depending on how much you need to learn about tuning engines.

If you want to buy a Sharktuner then I can do an initial walkthrough via remote access which will get you up and running. Fine-tuning and tweaking can come later, while you are enjoying the car. More info on my Sharktuner page, follow the link in my sig.

Many thanks for all of the replies.

I need to set 928 problems aside for a few days, but I intend to follow up on the Shark tuning suggestions as soon as I can.

Jeff – Pleasant Hill (San Francisco north/east bay area), not far from Bill Ball (….who unfortunately does not have a Shark Tuner....).
