well, im glad to see the truck is running right.

 

The Denali 6.0 supposedly has 25 more HP from the factory. And we have a different vehicle, but mine put down 280hp/310tq with just a Flowmaster cat-back. So similar numbers, although mine is all-wheel-drive.

 

yhea, yours is more power, plus the awd, but mine has a bigger tranny, and 14 bolt rear ect, so im right there, i wasnt sure what these trucks had, but im glad it is normal. i had the dealer do a warrenty exhaust leak and they wrecked a head and replaced it, so i always thought they may have screwed somthing up. but i think im ok.
