Does anyone that lives near Indiana have a Hypertech (or other) programmer and wouldn't mind doing my 2004 Blazer? I'm willing to pay some $$ for the effort! I'll drive to you!

 

A Hypertech has to be 'locked' to a VIN. If you program your truck with one, it won't program another one until it is unlocked from yours, thereby removing the programming you did. Plus, they are year range and engine model specific. It's doubtful anybody would loan you the use of one, you probably will have to buy it. This information applies to the Power Programmer III like I have, but may not apply to their other models.
