I have a sct x3 im trying to get tunes for.
how do i find out the computer or stratedgy code?

 

If that unit is the same as an Edge, you plug it into your truck and it reads it.

 

How do you get a programmer without tunes? Is it used? If it is, you're going to need to get a SuperChips dealer to unlock it for you. Your PCM catch code should be stamped on the PCM. It's a combination of 4 letters and digits.
