I have an 03 Duramax. I installed the AFE airintake, and a 4" exhaust that replaced the stock system from the turbo back. I also installed the Edge "Juice" computer system. I see great gains in power. Mileage increased by 2 to 4 mpg. With a 31' trailer and staying at 2000 rpms (about 68 mph with 3.73 gear) I get 15 mph. Stay around 55 mph, and it goes as high as 16.5. Empty around 20 mpg if I keep my foot out of it.
