[Cat-tech]

Yes, Pi Technology has made many programs for CAT over the years. So yes it is probably real to a point. CAT has many programs in it's Engineering Toolkit.

CAT ET itself has the ability to modify maps, modify the calibration if using the Engineering/Factory comet module.
CAT PSPS is what is used internally on the assembly line.

Do you have the ability to activate ET with that comet module?
