Hi knudles,
Welcome to the Chevy Forums.
OK, over 160,000 miles, let's see, How are those Catalytic Converters? Rattling any?
Changed the transmission filter every 40K as recommended?
Do you ever get a backfire?
Have you tried hooking it up to a vacuum gauge?
What's your transmission type and differential ratio?

My guess is it's a 1500HD truck being that it has the 6.0 in it. I had a 2002 GMC 1500HD and it SUCKED big time...just as you describe...no power....gutless wonder !! Sucked fuel and hardly got out of it's own way !!. My 2000 1500 X-cab with a 5.3 would out run and out pull it. Sold it REAL quick and bought my first D-max. A buddy also bought a 1500HD Chevy (2004 I think his was)....and nothing changed since my 2002.
Unfortunately I think it's the nature of the beast if that's what your truck is.......

With it being a 1500HD, which gears do you have? that could be an issue. Also, if you get a custom tune, not that hypertech, or edge programmer B.S., a true tune, you'd be amazed at how it opens up your truck... Trust me.
