    best mods to get my truck moving

    i currently have a 03 reg cab short box 5.3 chevy ss look-a-like. i am interested in things like a stall but have never had one nor do i know what will best suit my needs and what it will do for me. The mods i currently have are hypertech 93 octane tuner,gibson short chrome headers, custom crossover pipe 3 1/2 inch single exhaust,single cat,chambered muffler,throttle body spacer,throttle body coolant bypass kit,jba 8 mm plug wires,cold air intake, flex-a-lite electric cooling fans. Where should i go from here i wanna beat more stangs. Should i get my stock heads redone,where,how much? cam,not to big something trouble free.can my power programmer support such mods or will i need to detune it and have my ecm redone. give me ideas i am on a hp quest.
