Anyone know the differences in the speed cals available? (for changing speedo settings after a rear gear change.)

Dallas Mustang has these two available for my 2002 GT:

DM's "house" brand:

FRPP brand:

If anyone has ideas for alternatives, let me know, but a Diablo or SCT tuner is out of the question for now.

I believe the same guy designed both.

Get the dallas mustang one. With that Willie still does tech support for them but ford has none. He is on most of the major mustang boards with the user name TriBlkCobra. He can and will help you with any problems or questions you have.
