I use the ots map and its ok but it has been said by many that the ots maps aren't end all be all. A custom map will be better long term. These ots maps are very generic, you will get more power, a better fuel curve and better drivability, with a custom map. I have been very surprised with this map for my car, and honestly the only reason I haven't gotten a protune is because the closest real tuner to me is in plano tx. Quite a drive for me and that shop is by no means a cheap one.
