Hey all, just purchased a 2011 gmc with 24,xxx miles. It has a 5.3 liter engine. Already like my last car, looking to see what I can do to improve power and fuel economy. I know in a truck you can't get both. First off I'm looking at a cold air intake, which one would people recommend. I was told that by adding a cold air intake I could mess up the computer on the truck because it would not be used to that much forced air... Is this true? And I'm also wanting to add a leveling or a small suspension lift to my truck due to where I live and we get a lot of snow.

Any help would be much appreciated!!!
