I have a 2007 H3, 5 cyl engine. GFORCE claims that their chip on sale for $69 will increase performance across the torque curve by 60HP, increase fuel efficiency by 4-7 mpg with no adverse effects to engine.
Anyone know anything about this or have any experience with it?

I purchased one a few months ago, installed it and did not notice any significant improvements. I removed it and I'm about to send it back. Good Luck. Mine was a Powermax chip from ACDIRECT in Georgia.
I installed a cold air intake for my 2010 Hummer H3(# KN-77-3065KP) two months ago. Just this morning, the OBD II(On-Board Diagnostic-Second Generation) monitor lit up again. This is the 4th time that I experienced this code. What I did before to eliminate this Engine's Emission Error Code was just to reset the computer box by removing one of the battery's terminal cord.
Any suggestions on what would be the appropriate solution to fix this showing of OBD II code permanently. I am really worried that something might be damaged to my computer box in the future if this will not be properly addressed.
For the meantime, I am still going to unplug again my battery terminal to temporarily fix this problem.
