Can anyone help me add a 4L80 to my tune? I have a tune from a friend who has a 3bar, and 80lb injectors. Other than that we have the same engine, turbo, rear gear. I have a 2bar tune, and would like to use his 3bar tune. I have license his tune, but it wont let me flash entire to my car. What am I doing wrong. The first tune is the one Im running now, the 2nd one is my friend. I just installed the 4L80, and wont to drive the car.
