Bought a cortex tuner used . It says truck was returned to stock so that is a good sighn I thought. My only problem is I can not get it to read my truck and pick up my vin. Is there something I can do or something that I'm doing wrong it Sstill has the other trucks vin in the tuner

 

That would be a question for Scott@superchips. Either post in the Superchips thread or PM him. He's very good about getting back to people...

 

Thanks hammer I will go there and try and coxntact him.
