has anybody used the hypertech tuning program? if anybody has what did you think of the program?

 

I have contemplated purchasing the hypertech tuner. I have never heard bad things about them, but I haven't heard of or read about any 4.3l blazers with the tuner, so I can not comment. I would only be interested in it with their 87 octane power pack because I don't want to have to put in higher octane fuel...

 

When I called Hypertech they told me the programmer would only work on one vehicle so you wouldn't be able to change someone elses blazer that is the same year as yours. They also told me I would have to use premium gas. If the Programmer would work on more than one vehicle it would be worth the money.
