Just like the statement above. 2011 GMC SWB, lowered 5/7 and running a 5.3Kooks headers, Magnaflow dual exhaust, 6 speed auto and 3.42 gears. I have 140,000 miles on the truck and it runs pretty damn good,with an EFI Live tune on the engine and tranny. In cold weather the mileage drops off a little, but if driven responsibly I can put down 20 MPG on the highway.
