Hummer H3 Performance chips

[Hawkeye__8]

Im looking around to get a Performance chip for my '07 Hummer H3 and I want your guys' opinion. Does anyone run these in their own hummers? Says I can bump up the HP up to 35+ along with 4 more MPG, and we all know we can use that :giggle:. Will it be a wise choice?

I'm using a Hypertech . I got it to adjust for tire sizes , shift points and to read and reset codes along with a whole list of other things. I know a lot of others on here like their re flashed pcm's . I'm not saying one is better than the other , it's all about what works for your needs . I like a handheld tuner so I can change things anythime I want .

10 hp and 1-2 mpg would be the most realistic figure you could achieve from those tunes.

You're not going to get 35hp and 4 more MPG. You can go through Pcmforless, supermodulation, or get a handheld tuner.
