From my understanding there are 3 Chiptorque options.
The "J3" is the name of the service port on EEC IV/V computers. You can plug a chip into it to override the factory calibration with something different.
You can get a custom tune or an off-the-shelf tune using this. I beleive the $595, is for an off-the-shelf tune.
XEDE is completely different to the J3 Chip but also happens to be sold by Chiptorque.
The J3 chip is an edit (although limited in parametres it can adjust compared to SCT), and the XEDE is a piggyback unit.
