nice ride, keep the vids coming

will until the 09' come out let me know. that 5.3L will be stout with that auto 6-speed behind it.:thumbsup:

not only will a tune screw them up but wheel size bigger then 22' will do screw it to, unless they come factory with 22'. nothing to get bent out of shape over, i've owned 3 different GMC to and i loved everyone of them.:thumbsup:
