Thought I should post some pics of my truck. '07 Z71 4x4, 5.3 Currently sporting AEM cai, Nelson tune, Flowmaster 40, stock 3.73s, Edge power programmer that is now just a perf monitor since I go the Nelson tune, Line-x, Pace Edwards bed cover. New Comp cam from Nelson Performance going in next week...more to follow this summer (probably a front mount turbo).
