John Presing is an invaluable source of information for these cars (and many others). You should give him a call.

If you can't get the Ford Extender, you can get a Moats Quarterhorse or Tweecer board (there are plenty of others too) that plug into the stock Ford computer. You use a USB cable from your laptop to the board to change the stock settings.

There are a number of computer programs out there that you can buy online (or get for free in some cases) to change the strategy and calibration parameters once you get connected. You can change anything in the computer from how many RPMs your engine rises when the air conditioning goes on, to timing curves, injector size and slope, you name it. If it's programmed in the computer from the factory, you can change it.

I have the Moats board in my street car, and it works great. I use Binary Editor for software, which has a good interface and data logging capabilities. You can get both about $350 new.

You can download the software before buying it to get a feel for what it does. There is also a lot of information on the website that will help you get started. There are a bunch of tuning websites that are helpful too.
