There won't be a chip for the H3. I heard a rumor that Superchips is working on a programer. So far, the big tuner packages (HP Tuners, LS1 edit, etc.) don't have anything. There are many people interested in a tuning package for the inline's. GM left a decent amount of HP on the table with the H3 tuning (WOT delay, WOT timing, WOT A/F, etc.), even though the tuning is suppose to be more aggressive than the Colorado's.
