Greg I doubt very seriously if there is anything wrong with your truck
if the clutch is not slipping then most likely you are fine, reset the computer and give it hell:burnout:
Alot of the QC owners should be able to relate to this, the very first time you drive a 10 you expect tire boiling experience, well , it just dont happen sometimes
They are a tad slower than what you would expect and by 06 they had pulled timing on the bottom end to "take care of the clutch problem"
bone stock you should dyno 420 or above on a n RC,
but its soo true, some are very very different than others, you can take two QC's or RC;s same mods, linem up side by side, and one will flat out leave the other, and no reason why:dontknow:
but just deleting the cats, help emmensly on these trucks
