Need more MPG!!!!

I have an 05 Chevy 1500HD with 6.0L engine. I have a 3in body lift with 33s and flowmaster exaust. It has a poor alignment, I will soon to be getting new more street radial 33 tires with a new alignment. On average i am getting 10mpg... A freind of mine had suggested getting a k&n cold air intake, throttle body spacer, and programmer. Was wondering how much this will help me? And any other suggestions to help out on my mpg? :sign0144:

What do you mean by smoke and mirrors? And how much you reckon that the programmer and CAI will help? Is there any other mods that might also help?
