There are plenty out there - Superchips, Diablo, etc.
I have not used any of these (yet), but a quick Google search for Hummer H2 tuner will return a bunch of results.
The Superchips is popular with other H2 owners.

my buddy suggested superchips cortex, it has a good tuner in it and will do tires to 38" He has had great luck with his and i will be buying one next month i think. I want to get a good tuner for my exhaust, intake, and bigger tires.

Yeah, you can ADD an extra 60hp with a $69 chip! If you really believe that I have some swamp land for sale! jmo

well, after messing with my cortex for a few days, it is a nice tuner for trucks that have 38" or less tires on them. you can select everything you need to do and it will run great.
I wanted to tune for my 44s and cant with it... really sucks. I changed the gear ratio to 3.73 from 4.10s and got it corrected but with it set up like that, the torque converter doesnt hold well with the 44s.
I then set it to 4.56s and it runs great but my speedo is still off 10 mph with the 44s on it but it runs great on 91 octane tune. it would probably run much better on all of them with the 4.56 setting for the torque converter.
overall, great tuner for 38s or less, very capable with shift points and pressures. it has great stock setups too. I tuned our burb too and have had great results so far with that.
im in the process of trying to figure out if i can get a different setup for the tire/gears or if i will be screwed.
Any one know of a tuner that will do 44s?

There is an interface module that plugs directly into the output wires of the tranny and back into the harness to set what ever tire size and gears you have. It doesn't change anything but the speed signal.
The name slips my mind right now. try googling something like 4l60 gear tire converter adapter
it was about $300.
