Thank you!@GooseTuned is Cobb on steroids. You have to purchase a Cobb tuner (preferably from Goose) and it comes with some tunes. But Goose has put in the time and effort with 100's of hours in dyno sessions to fine tune the Cobb tunes making Goose custom tunes. Which after purchasing the Cobb tuner you purchase his tunes directly from him and the Cobb tuner becomes the interface to install the tunes to your vehicle.
