    Question HyperTech programmer III

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

    What about the GM model intake? As you said, they all pretty much perfom the same. Who makes the intakes for GM and does anyone have any feedback for these intakes? I love the looks of them. Of course I've got everything GM on my truck so I will still probably fo with GM. - GREAT post by the way, thanks.

    I'm pretty sure code 91 means that it is VIN locked.
