I just picked up a Hypertech & plan to load it up tonite. The main reason I bought it is I'm due for new tires soon and will be going to 37's. The extra power & firmer shifts sound good too. I'll post over the weekend (from Paragon http://www.elcova.com/infopop/emoticons/icon_smile.gif) as to how I like it.

After my truck died while programming and killed everything, I went back to stock and will not touch that thing again. Fortunately, I was at a Hummer Club event and the dealer reprogrammed it for me. Otherwise, it would have had to be flat bedded to a dealer.

OOOHHH! that blows. sounds like a glitch though. never heard of that before so im not too worried about it!

Update -

I had to send mine back to Hypertech for a software update. Got it back and installed the 87 octane program and increased the trans line pressure. I defintely notice a power gain and the trans shifts better now. Happy with it! http://www.elcova.com/infopop/emoticons/icon_smile.gif

Good stuff! Increase in gas mileage also or just power? what was wrong with the programmer, or was it just an upgrade?

dude i think u will be hard pressed to find an increase in gas mileage no matter waht, unless u dont drive the truck!!!!

[bigolH2]

yah, figured so, but some is better than none. the volant increased it up to 10mpg and that got me all excited so a little more and ill be even happier!

No difference so far.
