Using new DiabloSport Trinity to tune a 2005 Chev Avalanche 5.3L. After installing all the latest updates to the Trinity, the Trinity cannot retrieve the factory tune. The Trinity also says it does not recognize the CALID. After trying to retrieve the factory tune twice, it says that it may not be able to retrieve the tune if a performance tune has already been applied (which I am not aware of if one has).
