    Default Hypertech Programmer

    I just got a Hypertech programmer off eBay and plugged it in and get an [COLOR=blue !important][COLOR=blue !important]error [COLOR=blue !important]code[/COLOR][/COLOR][/COLOR] of 91.
    Of course it was cheap and buyer beware so I took a gamble.
    I think the old [COLOR=blue !important][COLOR=blue !important]user[/COLOR][/COLOR] left the prev VIN info in the programmer -
    Anything I can do? Or am I SOL?

    sol if the vin from the last truck is still in, he loaded it to his truck, and sold the tuner, you now have a nice paper weight
