I'm just wondering how all of you guys who tune your own vehicles got started?? I'm pretty sure that we have quite a few who do it themselves. How long did it take for you to get it down? Especially you Coyote guys. And I'm assuming that if you're still doing it, then you're happy with your decision? What are you using to tune? I'm not looking to start tuning mine today, but I'd like to do my own tuning sometime in the future.
