Alright gents, i'll try to sum this up as short and sweet as possible. For now i'll just give my problem because I have a plane to catch in 15 minutes. My truck is in Atlanta which i'm going to get back to tomorrow afternoon, i'm currently leaving Hawaii. It is currently programmed with an SCT xcal2 and the program it is currently on won't let my truck cold-start without it being plugged in. I figured before I dropped my truck off in Atlanta airport, i'd just put it back to stock so I wouldn't have a problem with the cold-start. Long story short, the tuner said the stock file was locked. Any suggestions on how to start my truck, since it will be cold???? Thanks in advance fella's.
