Has anyone installed a performance chip on their H3?

Here is a link to one I found, but I reall have no idea how to pick one out.

H3 Power Chip

 

After being somewhat involved recently with PCM programming on my H3..I've learned this chip tuner type only sets you spark in advance, a little more than stock...Stage 1, is slightly advanced = 89 octane, Stage 2, even more advanced = 91+ octane and a cooler thermostat because the engine needs to run cooler to prevent predetonation...So unless these contraptions do more than that, and I see no evidence of that.. like set tire calibration, MAF parameters, O2 parameters, Transmission shifting pressure, and a host of other settings, etc...The tuner performance you get for a $300.00 gadget, can be done by you dealer if you ask them for around $80.00.

 

Well, the one you linked says it's for 03 & up H2 & H3's w/ a 6.0. But H3's don't have a 6.0, at least not yet anyway, and they only came out in 06. So, I'd make sure that you get something for the 3.5, or make sure it will work for a 3.5. Ask the seller, and make sure you're comfortable with the answers they give.

As for the stage 1 and stage 2, it depends on what you've done to it, or plan to do to it.

 

A couple of months ago when I was looking for the computer programmer (had one in my 04 H2), couldnt find anything available. So I started looking at Canyon - Colorado forums. Since the H3 and these trucks have the same engine. So down the road it might be easier to look for a Canyon - Colorado computer programmer than one for the H3.

 

That's what I was thinking too. It may even be a little cheaper that way. It seems sometimes that if it has "hummer" in the title, they tack on a little extra, just for good measure.
