seriously, try a chip, exaust and 4.10 gears.
i remember seeing a turbo charger for the silverado 1/2 ton that mounts under the truck, and on the exaust. it was pretty crazy.
for maximum power from an exaust system, buy headers, and LEAVE THE STOCK MUFFLER/TAIL PIPES!! instead of spending $600 for an extremely loud, annoying exaust system. buy an electronic exaust cut out.
crfdude86 has a cut out on his dodge 1500, it is super loud, our as quiet as stock. all you have to do is flip the switch and close the cut out. it actually helped the power a noticeable amount.
