Have a customer at our dealership wanting to get a set of 3:73 gears put in his 2014 gt500. Can ids change the gear ratio for him or does he need a tuner?
Sorry if this question has been asked before but what is IDS?Although IDS shows an option to change to 3.73s, it doesn't work. He'll need a tuner. Search for my post on this topic if you want more detail.
