    Default 03 LB7 not recognizing license.

    I tuned this truck almost a year ago, he brought it back to install larger injectors, once installed i went to retune for them and its wanting me to license it again. vin number came up as a bunch of question marks and the serial number is no longer the same. any ideas of what could of happened or what i need to do?

    Thanks, Rob
