stock tune file 4500

Does anyone know where to get a stock tune file for a 2003 gmc 4500 with an allison? I have one here that I think is corrupted. Any help is appreciated thanks!!!

If you email me the current tune, I should be able to match the OS with a clean stock tune for you no charge. rob@atptrucks.com or you could email me the OS number and the speedo/gear/tire parameters in that tune.
