I have a friend who recently got rid of his truck. He had the Hypertech 30032 programmer and asked if I wanted to buy it. I did some searching and found it was good for the 2004 - 2006 chevy 5.3. I also found this online manual and on page 2 says up to 2007 Classic (which is what I have) so I bought it. When I plugged it in, it says my truck is not compatible with this. I am not going to return it to my friend but is there anyway of updating the programmer or am I just hosed?

Did he removed the "tune" off his truck before he gave it to you? It can only be flashed to one vehicle at a time. Either way you'll probably have the same amount of power with or without the Hypertech.
