Before you get the programmer you have to give them your vehicle information... They will create tunes for you based on your vehicle... You then apply that to your vehicle and the programmer is unable to tune anything else until you return the original vehicle to stock settings... But once you do that you can reuse it for another vehicle (after the programmer is set with tunes for that vehicle)
You can't edit them yourself, these guys that do the programming know more about these vehicles than we do anyways
..You can let them know what all you would like though. Mine i got 87 performance, 93 performance, 93 torque.
Hope that makes sense..
