And also for all you 5.3 guys to save a thread and just post it here what is the difference between the dod cams and the non dod cams? I plan on camin it and putting a decent size shot of nos on it due to the turbo kit being so expensive and no superchargers yet..

And I was just wondering what's the difference? Do I have to go dod or not I know I gotta tune thinking about the overkill tune but not sure on it yet. Thanks In advance.
