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.

sounds like a good upgrade,
thanks for updating us on the gears,
the exhaust should help also so update us once installed and you make a road trip
who did the calibration on the trans after the gear install?
get them to adjust the tune once the exhaust is installed, should help once tuned,

For the tune calibration I just modified my tune which Lewis Eaton provided me went from 4.10 to 4.88 , I contacted Lewis he gave me some guidance what to do once exhaust is on.
