Years ago when I got my first performance chip for my Aerostar (yes, an aerostar). I had to send in my computer module for them to analyze. Aboaut two weeks later I got the unit back with the chip in place. Got rid of the speed limiter (which was set at 90), made a tremendous difference in shifting patterns, and if I ran premium-I got more ponies (that ended about 1andhalf years ago when prices got crazy).
Anyway, my guess is that to get one soon, you would have to do something like I did.
The next question is where is the module hidden on this beast. Its got more electronics than I care to think about.
