The new 5.3L V-8 is SAE-certified at 355 horsepower (250 kW) and 383 lb.-ft. of torque (519 Nm). With EPA-estimated fuel economy of 23 mpg highway (2WD), it offers the best fuel economy of any V-8 pickup, and beats the fuel economy estimates of the Ford EcoBoost V-6.

The NEW 5.3L V-8 is... 355 horsepower and 383 lb.-ft. of torque...
Exactly. I was referring to the OP's older 2005 5.3L w/310hp & only 338lb.-ft. of torque. It's a real dog towing...

The OP just bought a new TT so he may not be able to run right out and buy a new/newer GMC. In 2013 I bought a 2011 Ram 2500 CC for $14K and the 5.7 Hemi has 383hp & 400lb.-ft. of torque. IMO the OP could sell his 2005 GMC & buy a 2011+ Ram 2500 without breaking the bank... The GMCs hold their value & the Rams offer the best bang/buck...
