Torque, HP, gas mileage upgrades
Looking into some upgrades and wondering if any have worked for any of you. I have a 2007 new body style silverado, crew cab, short bed, 4x4, 5.3, 3.73 gears. Have any of you had any increase in horse power, torque and gas mileage with dual flow master and K&N filter?
