Hummer H2 For those who like a little more gleam to their Hummer, the H2 offers a similar rugged look as the H1, but as a lower cost, and with more added features, making it almost a massive luxury SUV.

This is the initial start up with only mild tuning performed. Its got a ways to go. I'm not happy with the exhaust at all but do not know what I'll do with it yet.

A few hours of tuning, it still needs work.

Getting close! Love the bit of chop from the cam.

The computer is doing its best to keep the lope out of it at idle. My tuner can take care of it next session. He left it a little fat too. Now I need to tighten a few things up, go thru some basic heat cycles, tighten again, change oil and then we'll go from there. The stall speed is high and the shifting soft but he didn't adjust any line pressures or make any transmission adjustments at all. This thing is going to come out of the hole lick a gun shot.

Nice! Really going to have a nice chop once the PCM quits trying to compensate for the cam.
