Microday: Listen to these guy on the paint if you want a great job. They started doing Tuner stuff years before the H2 and can do everything you need. Here's the site address they don't want up because it's only a front page:
http://hummercustoms.com/
Now I can get a bad e-mail from them.
http://motorsportsauthority.com/ handles all the tuning for everything from ricers to HUMMERS while
http://hummercustoms.com/ takes care of us four wheelers.
