I live in Michigan I used to know someone that was good at retuning, he is long gone. I would like to find someone I can lean on to assist me at fixing my H3

 

I can make a pcm for your Hummer H2 with mods if you need and send it to you. Send a message PM

 

Your idea for Hummer H2 with mods sounds like a good plan. My 3.7L Hummer is an H3 I don't think what you are suggesting makes a difference other than parameters. Where are you located? Are you talking about making an executable file to a laptop and translate it to a VCM?
