I wonder if you drop the rear gears a little, what gear ratio are they now. should be in the 370 to 410 range. also what gas do you run. I just got back from Alaska over 7000 mi. of hills and mountain passes. gas was cheep in Alaska so I ran premium for a few tank fulls. 5.3 GMC seem to run noticeably better pulling around 6800
