hey guys, new to hp tuners, and the programming. just wondering how the purchasing of credits works to tune my car. I have a 2005 pontiac gto that i wish to tune on the dyno here in wilmington nc, and would like to know the cost to buy the credits in order to tune the car. again complete newb and don't understand gm's really that well have owned ford's for way too long. thanks in advance for any help.
