I have a 2009 Silverado 1500 with the 5.3. I am looking at a texas speed AFM/DOD delete kit but not sure what all I need. I am looking for something thats not super aggressive as this truck is my daily driver to and from work and school.
Does anyone have any suggestions for what drop downs to use so I can have a slightly more aggressive cam, and any required parts ( springs, etc).

Thanks in advance
