It is similar to that. You purchase the tune, then tell him anything you would like "custom", then you either 1) purchase the tuning cable (200.00) 2) have a cable sent to you (hold is put on yoru credit card until received). If you have a cable, you can at any time reflash stock tune, and do get a "discount" in purchasing other tunes, or free retunes if he comes out with them.
