Just bought a 2005 H2 SUT
 

My name is Jason. I just bought a 05 h2 SUT. It has a 6 inch lift a little wear and tear. Replacing ball joints next days off. Going to install a 4.56 dif. Eventually a new motor which is something im researching at the moment. Was thinking of a big block or stroking the 6.0. Was wondering if they or somebody makes can bus modules to trick or program ecm for motor replacement?

Welcome.

Look into a Truck Cam, Intake and get a Tune...

You could move to a 6.2 and do the same things as well.
