I picked up one for my X and reprogrammed the X. It's a company truck and it went in for service and it was reprogrammed back to stock. Can this be used on another truck or just my X?

 

Did you leave the SuperChip tune in the truck and then they flashed over it to stock?

 

They flashed it back to stock.

 

So they went over your Superchip tune? I ask because if that is the case, and they flashed over top of your superscips tune, you will need to go to superchips and get it reloaded. I do believe there will be a cost involved for superchips to fix this. In the future, always be sure to return your PCM to stock before you go for service. The other part of your question about using the superchips tuner on another truck....I am under the understanding that it is VIN locked to your truck. You can not use it in another truck.
