Hey everyone, new to this site and need some input. I have the 5.3 vortec, which i'm sure most of you already know that. I have installed an K&N cold air induction kit, a throttle body spacer and have a hypertech programmer which I have already played with. I want to get more out of what I already have (power wise) without any major modifications. Also, on a sidenote, the low end power is lacking some. Any help would be great.
