For '03 H2. Been used once. Not needed after turbocharging. Has been set back to stock and will work in '03 providing your dealer hasn't upgraded your PCM. $185.00 plus shipping.

Jonahs, Do you still have the Hypertech III ?
Also, What upgrade to the PCM do you mean ?
At 25,138 miles they performed "updated software, reprogram per bulletin" due to my complaint of a stumble on accell. I think the latest software loaded was the 12593058 listed at this site for my vin

Please don't tell me I screwed up and won't be able to use the Hypertech III #30019 now.
Thanks, Ed |

Doc, is it worth it? I'm thinking about one for my Yukon which is way underpowered.

When I first got it, I noticed that it seemed to have a little more spunk off the line, and definately shifted harder.... I just took the programming off yesterday to take the vehicle into the shop, and got it back today. It feels a little smoother if that makes any sense. Haven't hit the highway yet, but I'll run down it tomorrow and let you know. Will the H2 hypertech work with the yukon? Or do you need a completely different one? If it does, I wouldn't have a problem meeting up with you sometime to let you try it out...

Thanks Doc but my Yukon is a 5.3 Vortec. Hey, I know you are in Eastern WA but are you anywhere near Leavenworth? I'm leaving for the cabin tomorrow. We could get the kids together. Kacy

Sounds great, unfortunately I have to work tomorrow and I don't know what the wife's got planned for the weekend. Any idea about off-roading up in that area?

The Hypertech for an 03 Hummer is the same as the one for the 03 Yukon, a part number 30019. If they're both '03 models, it will work.
