The Equinox/Terrain Ecotec 2.4 isn't specifically listed anywhere on the site. Would it be exactly the same as the HHR/Cobalt 2.4?grometsc said:Trifecta is pretty well known among the Ecotecs.
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.
