Hi all, I have tried it twice now and em wondering what I have been doing wrong. I followed Justin's instructions and everything seemed to be going fine, the reflash said it was done then when i go back and read the pcm it still gives me the original os for a 4wd 6.0l van. It gives me the vin for the van that it came out of and not the vin that I put in for my truck. What em I doin wrong? P.S. Im bench tuning it's not in the vehicle.
