I had this same code issue when I tried to read a MIL code. I also had some driveability issue with the trans after the install of the tune. Do you guys all have 5/6 speeds? My auto just had to be rebuilt and it had only 75k miles on it and shifted perfect before the tune. And it wasn't solenoids in my trans. Just wondering if anyone else is having issue with sct tunes in the 07s with an auto trans.
