If you go on their web site(you can find a link on this site) you find a list of where the next meet is going to be, sign up and meet Justin in person for a tune. Or you can buy an auto-cal. You plug it in to your truck and drive with it and record data, send the data to Justin and will e-mail you a tune to log in to your truck. You can e-mail him or post a thread on this site and he will help you out.
